I've never personally had issues with animal liberationists. My undergraduate alma mater was chalk full of them, but fortunately they ran in different circles, so I never had the misfortune of meeting them personally.
However there were enough of them that we had a school-funded animal liberation group with "Animal Liberation" in its name (most liberationists will use the nicer-sounding "animal rights" rhetoric), and organized an animal liberation conference at my school, with two terrorists as keynote speakers. One was Peter Young
, I forget the other.
The school actually funded these speakers, which pissed me off and had me ranting to everybody I know. It's one thing to be content-neutral in funding. However advocacy of violence is actually prohibited by my school's own policies, but of course that was somehow overlooked. Then the other speaker, who was still in hiding from the Feds, backed out when the school didn't promise she wouldn't be arrested, and the animal liberationists screamed bloody murder, because the school wouldn't break the law to protect their terrorist.
Also, the group screwed over anyone at our school wishing to study animal behavior. Threats against the nearby state university's primate lab lead to all
students at our school being banned from the facilities for any
purpose. I had a friend in animal science who worked in that lab (she was from the uni, not my college), caring for their rhesus macaques. She told me that the only research permitted on these monkeys was behavioral: no medical research. Which isn't to say that I oppose animal medical research (I certainly don't, as long as it's not purely for cosmetic purposes) just that animal liberationists are utterly deranged.
