They look at meat, chix, as animals that should not be killed at all. Furthermore they feel that there are soo many bad things in meat that they will affect you in some bad way.
I actually got into an argument at a health food store when I kidded a worker there about chix - she stood her ground and chastized me for eating chix - I turned her in and a week later she was gone - as the manager felt that people should have the say of what they eat. I myself love veggies and salads but also love chix, fish, and some meat and dairy.
They had this thing on tv some months ago asking regular folks to eat only veggies for a month and for vegitarians to eat their food plus they had to eat chix and meat and fish at least once a week for a month - some of the vegitarians had to admit that eating a little meat did give them more energy and felt a little better. I wonder why???
