I never chose to start thinking this way. In fact I am so resilient that I tend to forget about it , go and try again telling myself that I am the one with the problem and shouldn't blame others for not understanding the way I think, since I'm the one who is different. And then they start talking and I start staring in disbelief again, they say something strange that I will analyse for a few hours afterwards until I pinpoint the reason why it made me feel uneasy.Generally, it was something insensitive or downright insulting, that i didn't understand immediately as being so, because I still don't understand why somebody would attack me out of the blue. I try hard to remind myself not to let my guard down, because I forgive too easily and approach people the way I would like to be approached, and it always ends up in me getting hurt.
For me, seeing them as a "group" and calling them "them" in my head helps me remember that I will not be automatically be accepted or treated in a friendly way, and it's a lifelong process that is only moving slowly because of my tendency to forgive and forget, I NEED to separate myself from them mentally , and learn that there are mean people out there, which I know intellectually but aparently can't emotionally process.
Laying down all the reasons why "NTs are mean and hurtful and stupid" is a sort of survival process, where you train your brain to stop greeting everyone with a wide open heart, because the more you get hurt , the more your self esteem goes down. It doesn't have to last forever, as when you finally emotionally accept that not everyone will like you, you can start to balance your views about NTs in a more normal "some are nice and smart, some are stupid and mean, and I need to know how to differentiate them" view, but I'm not there yet. For now, I'm still too young emotionally, at 33, and I need to grow out of that intinctive trust, by going through a "learnt distrust" phase, until I reach the adult way of approaching strangers, which is: don't open up until you know if this person is nice or mean.
