Ever hear "don't yuck peoples yum". Not everyone enjoys Devil's Advocate, probably because it's most often pulled out to harass people who are already in a marginalized position. You're on an aro forum presumably for a reason having to do with being aro, wondering if you're aro, or trying to figure out how to support an aro friend. Why does one little aro headcanon threaten you so much? Aro people already have no rep, and now you want to ensure we can't even pretend? This thread is supposed to be for fun. If you don't believe a headcanon, just move on. There is no positive reason to turn this into a fight. That's actually really shitty.
Please go introspect on the internalized bias you've been displaying. This is meant to be a safe space for aros, and this attitude threatens that.
