Just for the heck of it, I'm going to put my own spin on this. I'll inevitably do it in my own roundabout INFP way. And the subject is kind of a tangent; but maybe it will broaden the discussion a bit.
I agree with Proteanmix's point here. The mods and admins have indicated once or twice that they would prefer a broader mix of MBTI personality types here and that they would specifically like to see more SP and SJ members. If iNtuitives are routinely trivializing Sensors or blaming them for everything that's wrong with the world, that's obviously going to be a deterrent to the recruitment of Sensor members.
On the other hand, this is an MBTI-oriented message board and we tend not to tiptoe around MBTI differences here. Introverts bash Extraverts for being gabby and brain-dead. Extraverts blame Introverts for not trying hard enough to reach out to others and they have no sympathy for the social woes of Introverts. NTs call NFs oversensitive wimps, and NFs call NTs cold and cruel. And so on. We all know the stereotypes, and we regularly exploit them for laughs and occasionally use them to take a dig at other members.
In this kind of atmosphere, it's going to be tough to impose a consensus on how to deal with MBTI stereotypes about Ss.
My own personal opinion: I wish people would go easy when using negative MBTI stereotypes. For instance, I don't much like the "Name 3 things that suck about NTs/NFs/SPs/SJs" threads because of the put-down nature of those threads. But on the other hand, I can also see the argument that this is an MBTI message board and it's better to get the stereotypes out in the open as part of a frank discussion of MBTI subjects.
Also, some folks may remember that when I was participating at INTP-Central I complained about the name and description of the non-INTP forum; but that was because I thought the management over there crossed a line when it institutionalized typism by making it part of the formal message board structure. (INTP-C management apparently disagreed, and that's their prerogative.) On the other hand, I personally don't mind it so much when other individual members bash INFPs. I can give as good as I get. Besides, INFPs have strengths of their own; I can sit out the threads where I'm weak and then jump into a thread that fits my strengths and dominate it, and good luck to any of my detractors who might challenge me on my own turf.
Anyway, the point of those last two paragraphs is that I can see arguments both for and against allowing Ns to air their personal grievances about Ss. I don't really feel strongly either way.
Meantime, I also keep in mind that (in my experience) Ss tend to have a lot of disdain for ditzy, schizy, whiny, N dilettantes. From the Sensor point of view, Ss are the sober, experienced adults, while Ns are the idealistic starry-eyed teenagers of the world.
Ns brainstorm and fantasize about how nice it would be to get rid of all cars in order to reduce the greenhouse effect. Meantime Ss are laughing at the Ns and shaking their heads, because the Ss just finished a shift working as part of a team of cops and paramedics untangling a high-speed six-car pile-up on the highway. It's all fine and dandy to brainstorm about life 50 years from now, but in the meantime someone needs to have a Sensor's mastery of observation, detail, and procedure and the presence of mind to handle the real-life emergencies happening on the roads right now.
Ns bitch and moan about globalization issues or the white-collar rat race or the paper chase in bureaucracies. Meanwhile, S admin and management specialists laugh at the dilettante Ns who have no idea what they're talking about. The S specialists have read through thousands of pages of corporate directives, administered pension funds, granted education allowances for dependents, worked up merit allocation coefficients for pay increases for employees, sat on grievance tribunals for disgruntled workers, audited budgets for departments, etc. They know the corporations aren't going to disappear anytime soon, and they know why.
MBTI stereotypes cut both ways. Ns tend to see themselves as visionaries and they see Ss as dreary, unimaginative, fussy drudges. But in my experience Ss tend to see themselves as responsible, clear-eyed, sensible adults and they see Ns as oblivious, whiny, teenaged dilettantes. And in that light, name-calling may only be a facet of a larger problem.
I sometimes wonder what Ss think about the discussions that take place here on MBTI-Central. There's a lot of whacked-out, dimwitted theorizing about how nice it would be to kill off big portions of the population, get rid of organized religion, get rid of the corporations, etc. As the real-world "adults" of the MBTI spectrum, Ss probably aren't going to have much to say in such discussions. And even when discussions are more down-to-earth and results-oriented, Ns frequently discount any first-person experience as anecdotal, a mere snapshot of a point in time having no bearing on future trends. So you get a big disconnect between the Ss with their excellent powers of observation and first-hand experience of the world vs. the Ns who deal in overviews and theories and only want to discuss broad trends and future developments.
I think the name-calling may be a symptom of this larger disconnect in world view. Adults live in the present and take rules and schedules seriously; teens are oriented toward the future and value idealism more than a paycheck. Adults get in a rut and lose sight of the possibilities; teens are blind to the line between sense and nonsense because they've never had to put their money where their mouth is. If adults and teens refuse to consider each other's point of view, then they aren't going to enjoy each other's company. Mutual name-calling may be a complication, but it's not necessarily at the root of what's keeping them apart.
On the positive side, some Ss continue to post over here, perhaps to broaden their own horizons and learn about Ns, and perhaps to remind Ns that a real world exists out there and recount some first-hand experience to help Ns bring their theories back down to earth and anchor them in reality. And in the meantime by participating on a mixed-type message board Ns presumably indicate that they are open to opposing views, at least in theory.
If the quantity of Ss ever reaches critical mass, we'll probably see more name-calling rather than less. As I said above, in my experience Ss tend to have a lot of disdain for ditzy, schizy, whiny N dilettantes. It doesn't always come out as irritation; sometimes Ss feel positively paternal and protective toward the loopy, occasionally-brilliant, occasionally-vulnerable Ns. But inevitably there is going to be irritation and defensiveness, and frictions on the message board are going to lead to abuse of stereotypes and some fireworks at times.
Hopefully in the long run everyone can remember that this is a mixed-type message board, understand that the traditional stereotypes aren't going to disappear anytime soon, not get too worked up when the stereotypes are abused, and remember to stay open to other viewpoints.
Just my own opinion, of course.
