Is it because they aren’t attracted to adults or because they don’t like a woman reaching an age where she can make her own decisions?

Such immature insults with unsavoury implicit messages. There are plenty of legitimate reasons to hate conservatism. Implicitly calling all conservatives (you can never extrapolate anything besides the thing that binds them to a large group) either teenagers or ephebophiles (it’s not clear which, although I suppose teenagers are usually ephebophiles anyway), is obviously untrue, and also wouldn’t be an insult if it was, since ageism doesn’t make good insults, and neither is calling someone an ephebophile, since it means nothing as long as they don’t act on any illegal impulses.

I think some states let you get them with parental permission

Or maybe all those girls I saw in middle school with earrings just had it done at home?
