Adding to this, it's not only non-Aces giving this type of criticism but I've seen other Asexuals too, specifically those who are repulsed. And I say this as a repulsed Ace who also HCs Alastor as a repulsed Ace.. DON'T tell other Aces how to represent him. Asexuality is a broad spectrum.
I’m gonna make a general announcement again okay: I’m Ace. When it comes to Alastor, you can argue with the wall if you really feel that mad about me making him hot and heavy sometimes cause I legit don’t know how else it needs to be explained: stop babying Ace ppl please 😭
