Her money and her blind fans who continue to enable her and ignore the fact that she is a horrible person.

For a professional writer you'd think she would know that a quotation (even a fictional one) requires quotation marks around it to make it clear to the reader that it's not what you are saying but somebody else. Perhaps this makes more sense:

"Refusing to accept that people who don't like sex belong in the gay category is akin to wanting segregated bathrooms in the 1950s, John," as approximately a thousand gender activists will inform you once their hands stop literally shaking.

She's mocking the people who replied to her.

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...

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

Sounds like Voldermor was inspired by her own persona
