Fish is meat.
I'm a vegetarian I have been for about 6 years, I don't like meat because I don't like the flavour or texture. When I was a kid I didn't really eat meat either.
I'm not an animal activist, I don't care if others eat meat, but I won't.
As for the killing of animals, I'm not stupid enough that I think it's going to stop, it doesn't bother me if the way they're killed is humane. I don't like to any animal suffer.
