They're 16 years old. It's perfectly natural to be a complete idiot when you're a child. I was a bog-standard libertarian at their age, there's still plenty of time to turn around.
sure, maybe 20 years ago in an AIM chat room. Twitter lets you show a birth year so, unlike an AIM chat room, twitter has a mechanism to show age. that's why it made no sense or wouldn't stick out. should be age/pronoun/location in the bio, then it would still fit the format.
