Personally, I am a vegetarian. I don't eat pork or any other meat. However, that is a personal choice.
I am irritated by dietary choices that are demanded by religions; I don't think it's anyone else's business what any person decides to eat.
If I were to reverse those dietary laws, how would everyone like it if I were to rule that everyone had to be a vegetarian?
I know that will never happen, and whether or not I think it should happen is irrelevant. People are going to do what they are going to do, and it doesn't matter what anyone else thinks about it.
Outside of actual criminal behavior that is a danger to society, we are free to do what we want; we have free will. We can use that to make wise or poor choices, but we each make our own choices.
"dashingscorpio" has it right when he points out that we don't get out of life alive. While we are alive, we should simply make the best of our life, and let it go at that. Eat what you want, but leave other people to their own choices as well.
