I can somewhat understand that there might be a lot of confusion when for example you meet someone and you seem like an excellent match but then they don't seem to have any sexual interest in you. If you don't know about asexuality, it can seem very confusing and you might feel like they don't want you for other reasons. Such feelings can lead to resentment. Or even if you do know about asexuality, it might frustrate you if you're a very sexual person.I had to Google this as well....as far as people not wanting to have sex....
I really dont understand how anybody could get worked up over someone else not having the desire to bang.
Obviously none of that justifies any of the bigotry though.
Then obviously there's the rawer side of people being really shitty. People tend to hate on anything different unfortunately, and while gay and bi people get a lot of shit too, even the bigoted people can't really say their sexuality isn't real (though the worst bigots do try to change it in vain). But with asexuals it's so easy to think it's not real and sort of erase the existence of asexuality in your mind.
It sucks.
