What bothers me about the whole “children shouldn’t be identifying as ace” thing is that like… You can have a sense of who you are even before you start having sex or even have a sense of your own sexuality. You can be acutely aware of how all your friends talk about having crushes or talk about sex and what they’ve heard or what they want to do and you just don’t get it.
Kids can know that they’re gay/bi/trans at a young age. Kids can know that they’re ace/aro at a young age.
And if they get it wrong? If they aren’t interested in sex because they’re young and just aren’t ready for it yet…. so what? They grow up and get a better sense of themselves and leave that label behind…? Big deal.
