Good discussion about parenting techniques. Like Mempy, I approve your philosophy wholeheartedly.
Don't worry about the little jibes at INTJs. The younger INTJs get a kick out of playing into their own stereotypes and exhibiting what hardasses they can be. So a lot of the message board banter concerning INTJs plays off that stereotype.
It happens with all the MBTI stereotypes: INTJs are howling voids of evil, INFPs are hypersensitive creampuffs, INTPs are scheming geeks, etc. Playing into stereotypes is probably beneficial for the younger folks in that it helps them find a quick easy slot to fit into while they establish an identity on the message board. Engaging each other on the basis of stereotypes is a way to get a quick handle on each other and maybe do a little (mostly) harmless teasing. IOW, it's meant well.
But if you're older and have developed yourself on past your stereotype, you may have to make an effort to ignore that banter. Sometimes it just gets in the way of more complex messages or interactions. [shrugs shoulders]
I'm enjoying your posts. Hope to see many more.
