First off, you're wrong. Absolutly wrong. If you don't know anything about the religion at all, don't say that they are wrong. Being judemental is a problem I see with many people, including you, and is one of the common things that start fights.
Just to clarify, Buddhist believe that life inside vegetables "reincarnate" or "leave" faster (Called Xue Ling by Chinese) from physical material left behind on Earth, than the life of any Chordata phylum species.
Killing is a natural way of life for survival. Not pleasure for "eating meat". We live in a world today where we can literally not eat any meat, because we have sources elsewhere to supply the neccisery nutrients we need.
Also, evolution (or if it makes you happy, your God) made it possible to eat meat for that survival reason again. Mammalia was only ment to eat vegetation. Years of evolution (survival of certain genetics allowing a special capability for survival) (or if it makes you happy, your God) changed the teeth for us to survive longer.
No, I'm not Buddhist, or Chrisitan. I'm just clarifying for you.
