Well, on the other side of the spectrum, I'm certain that some Fs have problems/lack understanding with Ts. I don't, but others may and do.
But that's the whole point of this forum, is it not? To help better understand others personalities. At least, that's what I see it as. Whenever I come across something I don't quite understand and related to personalities, I usually find my answer after being here and talking for a bit.
I don't think it should be seen as insulting, too. We all think differently, act differently, and have our own views. Sure we are going to disagree and have disputes and rule out personalities and people as irrational and wrong, but what that represents is lack of understanding. Spend enough time here and you'll have some of your answers. Spend some time in the real world with an open mind, and you'd be damned not to have all of your answers fulfilled.
That's my summary. Like it or hate it.
