I wouldn’t really call myself asexual because I’m still attracted to women, but I haven’t acted on it for several years now (social anxiety, frustration, that’s a whole can of worms). My friends absolutely do not respect that. I can absolutely see how people would be casually and openly prejudiced against asexual people, even if they’re open-minded about any other kind of LGBTQ person, and even if they’re LGBTQ themselves.
