First let me say, that I LOVE Dawkins. I think he is absolutely brilliant! As for the meat eating thing, I don't think that eating meat is immoral. I can kind of see why he does, but for me, I dont think that is so. As far as the sexism aspect of it, that makes no sense to me because people eat both sexes of animals all the time. Racist to eat meat? I don't agree with that either, but a person can say a few things that don't make sense to everyone, and still be an all around genius. Dawkins is of no exception.
