Morrissey became vegetarian at age 11, inspired by his mother, a long time animal rights activist and vegetarian. He is very outspoken on the issues and has encouraged many people to give up meat through the song and album Meat is Murder. Meat products are banned from Morrissey concerts.
I see no difference between eating animals and paedophilia. They are both rape, violence, murder. If I'm introduced to anyone who eats beings, I walk away. Imagine, for example, if you were in a nightclub and someone said to you "Hello, I enjoy bloodshed, throat-slitting and the destruction of life," well, I doubt if you'd want to exchange phone numbers".
