Re: When I was at college...
Vegans are basically following a belief system. Just like Christians and Muslims. And because it's a belief, and all beliefs can conflict with each other, everyone can take the piss out of everyone else. So don't feel ashamed about criticising someone's beliefs. The basic human right of free speech means that you have the right to offend someone else because they will be offending you, be it by spouting some religion or political opinion.
