If you deanonymise, you'll have to do it on a general basis. This would include investigative journalists, whistleblowers, protesters etc. Surely you can see the net-negative we'll get from that.

An assumption I disagree with wholeheartedly. People say and do even more heinous shit in person all the time. You yourself said your locals have become more aggressive. Do you think that if we were like, "Hey, if you wanna continue to talk shit, you have to tell us your name" they'll just be like "oh okay you know what you're right I was wrong I love minorities" or do you think they'll just become even more aggressive? Do you think that'll lead to more understanding between people? Or just more violence against minorities?
