I found this site and it cracked me up! It's called Vegans Are Evil and/or Vegetarians Are Evil - it seems to be the same site.

They had a page on the types of vegetarians that was kind of funny. I like what they said about Pescetarians, or vegetarians who eat fish. They said, "Someone should tell these folks that fish are not vegetables, but are, in fact animals that live in the water."
