The reason I support anonymity is actually because I've experienced the results of not having it in the real world. As someone raised agnostic in the middle of the bible belt during the gestation of what is now open Christian nationalism, I got to see exactly what happens when you aren't part of the in group. Starting in the 3rd grade, gangs of kids would make a game out of keeping me away from the playground equipment. To allow me to play there would taint it with my sin. Group projects would have me abandoned or assigned to work with the teacher. This persisted through highschool where I was barred from joining 4H because I wouldn't pray before every meeting and a teacher failed my participation grade every day for not doing the pledge of allegiance. A decision supported by the SuperIntendent.
Now the same people that prayed around the flagpole in the mornings to prepare for a day of telling me I deserve to burn in hell are the people who dictate the highest law of the nation. It's luck enough that I'm not also trans or brown became those are the people they picked to destroy first. That doesn't mean they'll stop there. The death of internet anonymity means that when the powers that be run a kangaroo court before my execution, this post will be evidence of my commitment to sin and irredeemability in the eyes of Trump's God.
I truthfully want a world where anonymity is pointless, but until we live in a world where those in power are without any malice it simply isn't safe. I hold no delusions that my anonymity currently is any actual protection either, but until it's gone it's another hoop they must jump through to get to me and at the very least I can die being petty and difficult.
