She hates asexual people for the same reason she hates transgender people, they're not conforming to her view of normality.

There are a strange amount of people who seem to hate the idea of asexuality and this unfortunately includes people from all swaths of life like the LGBTQ+ community. I've seen too many gay people say hurtful, and frankly hypocritical, things along the lines of asexuality not existing and being more akin to a disease. It seems that while more people have become aware and accepting of homosexuality, they still don't understand asexuality and it scares them. Sad really. But luckily there are still lots of kind souls out there that will be accepting of anyone who's accepting in return. Maybe they can show everyone else the way...

I used to work with a guy that used to get himself wound up cause I don’t sleep with my partner enough.
