Please, answer this for me!?

I keep meeting people who tell me how they are vegetarians and think that eating meat is wrong. I asked why? and i was told that eating any type of meat is cruel. That killing an animal for food is wrong. I have coworkers that literally live on dry beans and other crap. A girl said to me that she could not bear the thought of a defenseless animal being killed for food. I looked arounf and started to laugh my *** off. And this is why....Nearly all of them were either smokers, did drugs or were heavy drinkers. Why is it that they believe in saving animals but dont believe in saving themselves. Smoking kills you, drugs kills, and drinking does too. If you are gonna be hard core about it do it all the way DAMMM!
