When I say something, it's not open for debate. You can continue the argument by giving me new topics to delineate on, but you can't refute something I've said because I said it for one reason: it feels like the truth to me.
If you're refuting one of my statements, you're attacking me personally. The only way to ever get me to agree with you is to get me to spin my argument in circles until I realize that I'm wrong. If you try to tell me I'm wrong, I'll give you the finger and tell you to fuck off.
Mostly because in High School I got tormented for my Fi, so now I get very defensive when someone directly disagrees with something I say. If you want to understand what I'm saying or let me work myself into realizing that it's wrong, that's one thing. To come at me directly is an act of war, and I immediately close up shop and clamp down my clam shell when someone's being aggressive.
This is why I do not get along well with Thinkers. I don't even get along with strong-voiced Feelers. If someone comes at me, I will resist. I've just spent so much time having my Fi bullied that it's a triggering defense to an almost alternate personality. I use my shadow functions often as defense mechanisms.
