Fetishization of a group of people is a way of prejudice that not enough people know about. You can be attracted to different genders, or different types of people, but you cannot think of a group/gender only in a sexual way, because you aren't thinking of them as people at that point, you are thinking of them as your toys to play with. Honestly I can't believe how there are so many people that do this. There aren't that many compared to the amount of normal functioning humans, but you encounter so many different people in a week alone that its probable you will see some. I just can't comprehend how they do these behaviors, because even most homophobic or racist people would know not to do that to anyone. At least I can understand homophobia or racism, because it is passed down from parents most of the time (not saying that it isn't a horrible think, I just understand why it happens). But I don't know how people even do this, as it isn't something that is widely accepted by any group of people. I'm sorry you had to come into contact with this parasite of a human, and hope something similar doesn't happen again.
