I understand the philosophy. Animals can feel pain, therefore it is immoral to kill them for human pleasure. An animals preference to live outweighs a humans preference to kill it.

Having said that, i am not a vegetarian because my taste buds prefer meat as opposed to vegetables. I personally do not kill animals, therefore i find it justifiable to eat them. I wouldn't want good food to go to waste when there are starving people in Africa and anywhere else in the world.
