Hmm, I've been through various stages of vegetarianism since I was 10 (1992). Most of the time I was a piscatarian (ridiculous word - it's just a media term), but then I became a lacto-ovo vegetarian, and then a vegan (for a little over two years). At the moment, I eat fish but no other animals/animal products.
I don't eat animals for ethical reasons. I don't want to eat something that has been bred to die, something that just spends its entire life in a field. I think that kind of sucks. I'd be a bit annoyed if I just stood around in a field all day, and my one trip out of said field proved to be a bit of a one-way experience. That's how I justify eating fish, although I still feel pretty bad about it. I won't eat anything that has been farmed, though.
I don't eat dairy because I don't think it's healthy. Those animals are all pumped full of hormones and antibiotics. Plus, I'm pretty unsure of milk. I don't know of any other animal that drinks milk past infancy - seems a bit weird to me.
