This is terrible ace representation, I'm sorry. Saying we can't experience romantic attraction is severely hurtful. Say they're platonic if you want, but don't use one of the least represented and hear visible LGBTQ+ orientations as a way to hide the visibility of gay men in media. It's not representation if it has to be clarified with a tweet like Legend of Korra, slapping it on after the fact. It's not good enough to be in the subtext - it has to be in the TEXT
