People actually born in 88 forever subject to the username police. How dare you not be born with preexisting knowledge of nazis and their dog whistles.
You're allowed to change your nickname. Many of us go our whole lives without putting our birth year in a screen name.
People born in 1988 is 37 now. Honestly, I don't even question whether screenname88 is a Nazi. Anyone between ~25 and 60 with their birthday in a screen name is a weirdo too.
