I still partially suffer from the delusion that if you explain things logically and systematically, most people will abandon their emotional prejudices and respond to logic. But I don't suffer from that delusion as wholeheartedly as I did in the past. So if there's a fundamental difference, it's that I've accepted the fact that most imbeciles will never 'get' me and I shouldn't allow myself to get so upset about it.
I could have completely lost my mind or became a junkie or abandoned all sense and judgment and committed some rash, stupid act that would have sent me right back into the cage. Instead, I chose to be happy - but not so much for the sake of happiness as for spite.
There were people whom I considered friends or loved ones who either abandoned me or betrayed me in ways I'd never have suspected. But there were others who had been barely acquaintances of mine whose loyalty and efforts on my behalf made me realize that not everyone was as inherently rotten as I'd previously believed. So it caused a violent split in my view of humanity - people turned out to be far worse and far better than I'd ever dreamed possible.
I don't think it's entirely paranoid to suspect that one day, you won't be able to so much as question the primary tenets of anti-racism without going to jail.
Here's an easy one: "Race is an entirely social construct." No, it's partially one, depending on how any given society seeks to define it and its implications. But there are basic things such as skin color and hair texture. Even a Martian who'd had no exposure to human "social constructs" would be able to spot those differences. But no Martian, as hard as he tried, could point at a "culture" or to "equality." Those are the social constructs. Those can't be measured in the same way as human DNA.
