1. don't plants have feelings too? i read that they have rudimentary nervous systems. so when they prove that as well, are you going to just eat fruit?
2. you need to live your life and to enjoy it, and good food is one of the essential things in life. otherwise life has no point.
3. who says an animal feels pain the same way we do? no one knows.
4. a lot of people are going to be unemployed if we all become vegetarians. who's going to employ them?
5. that UN "long shadow" report has been disproved, so please spare me the environmental argument.
6. if the environment is so important, why do you drive? why do you turn on lights when it's unnecessary? can't you flush less and put up with a little smell?
7. if eating meat is so detrimental to our health, wouldn't we have heard about it by now? humans were born to eat meat - the caveman diet really works.
8. it's part of our culture and tradition to celebrate by eating [insert appropriate animal]. it's in our blood (really bad pun intended)
9. fruits and vegetables don't really prevent cancer, contrary to what you believe in. you will have some long term health problems from it, like vitamin B12 deficiencies.
10. my God, the one true God, created animals for my consumption. but since you're not going to heaven anyway, it doesn't matter and you wouldn't understand.
there are more here, but these ten are the ones i come across pretty often.
