I used to like most everyone. My GF used to call me a cockeyed optimist because I could see the bright side of almost anything, and gave people the benefit of the doubt. Twenty years of rejection and worse have made me bitter and resentful toward NTs, and watching the same thing happen to my son has been crippling. I have never been a fan of the Autistic superiority mentality, and I'm still not. NT society's culture of rejection, overtly or tacitly supported by 99.9% of NTs, taints them by association.
There are, of course, exceptions for decent individuals, regardless of quirks (or absence thereof, as the case may be). Why are there so dratted FEW of them, though? (Decent people, not exceptions. Well, that, too, I guess.)
So, yeah, it's EXPERIENCE that's turned this once gentle soul into a hater.
