to be fair, from a distance, it is an understandable mistake:
even if one isn't into the "N>S" schizm mentality, it would be incredibly difficult to not get that atmosphere everywhere around this community from both ends - the "
i am so intelligent but so misunderstood" N vs. the "
we are down here on earth keeping it real!" S. its entirely natural that people will absorb that atmosphere, even if they aren't willing to consciously drink the kool aid.
regardless of your type and functions, you do - entirely - vibe of the later, it's the atmosphere you project around you, and from what i've observed much of your value system points towards that direction.
I wouldn't care much except that Se REALLY could not be farther from the truth for me. I also prefer people interact with me a bit before making definitive judgment calls.
you are right that 1on1 and real time interaction would leave people more informed, but most people here don't go on vent or tiny. there are plenty of other social groups and networks here - people exchange FBs, skype, tweets, emails, PMs, write on each other's visitor boards and even know each other in real life, etc... but for people you aren't connected too in any means by that forum, it's perfectly reasonable for them to make conclusions based on the information they have - what they see in the forums. in fact i am sure there are some people here who don't have contacts from here beyond it at all, and would be limited with any conclusion they can reach on anyone exclusively based on what they have from the forum.
and.. well, you don't exactly Ne much in public - if you don't have at least one or two people you are comfortable with, you rarely ever go there. likewise, Se - whether its there or not - isn't as visible in an online medium.
i am not saying OAs correct - function-wise she isn't - and i do get why misconceptions like this can be frustrating (this reminds me of when i thought you're avid sims fan because you played it for a few days), but based on what you display and what material she would have to work from, added with the fact you used to think you are a sensor, it isn't a far reaching misconception.
