It's so funny how so many non-ace, non-aro fandom purists insist that shipping Alastor or portraying him in sexual situations is some moral failing "because he's canon ace and probably also aro."
Meanwhile the majority of the actually asexual members of the fandom (me included) look at him and go "yeah he fucks, but recreationally."
All the while the majority of the aromantic members of the fandom (that I know) ships him with at least one other character, but usually in a qpr rather than in a romantic relationship.
Like, it couldn't be more obvious that the fandom purists just want to prevent people from having fun. They're just incorrectly using the term "erasure" as an excuse to bully people over a fictional character.
