I'm sorry to hear that. The thing is, you mainly hear from those who are the most vocal, and those tend to be the most angry and therefore unreasonable. And those probably had their fair share of verbal (and/or physical) abuse from meat eaters, as vegans are hated on by a much, much larger part of society than the other way around. (That doesn't justify their hate, of course)

It's all a self reinforcing dynamic of groups riling each other up, unfortunately.
