>If someone I was friends with made racist remarks, they wouldn't be prosecuted for that. But I would stop being their friend.
So you want your friend to be able to anonymously express their racism while being able to hide it from you? I can't imagine advocating for that as a desired goal rather than a negative side effect.
>Similarly if I was the only one in my friend group against racism and advocate firefly against it, they would probably stop being my friends.
If we are talking about a society level problem, I think it is a little silly to think a society as toxic as this hypothetical one could be saved by anonymous internet posting.
For the record, I'm not as against anonymous posting as the person who started this specific comment thread, I just think this line of argument is advocating for a band-aid over bigger issues.
