I've been vegetarian for over a year now. Just the thought of eating meat makes me queasy :S My mum's not happy about it, but I make things for myself so she doesn't complain as much xD
Redd, fish and poultry are usually given some leniency. Poultry, would make me sick. Fish, wouldn't. :3 Its not so much of a meat. It won't screw you up.
But I never liked it anyway, lol, and its not like fish are going through as much abuse/causing greenhouse gases.
