Are you on the autistic spectrum by any chance? I am on the spectrum and often feel extremely similar.

And don't get me started on societal issues. It's impossible to even point out the nuance in the world's issues without being called a nazi. These are issues I don't claim to be right on, all I do is point out nuance that does exist and try to actually discuss reality instead of a made-up situation that is far from the truth, but people either refuse to see it or aren't able to. I don't know.

Basically I live my life never being able to say what I think without immediately becoming a pariah, and it gets to me because I've never felt accepted anywhere.

Even posting on the internet, I always get downvoted to oblivion whenever I point out valid concerns.

I think you will feel very at home on SaidIt, as that is pretty much non-existant here :) . No bannings for controversial opinions either, which I have gotten or almost gotten on other sites and certain subreddits.
