I've had foie gras before... it is yummy. Then I became one of those rascally vegetarians. I could really give less of a shit what other people eat... as long as they can eat the food and appreciate it (I know gastronomy is really like an art) then that's fine with me. Do the same with my eating habits and we won't have a problem.
I'll withhold my personal opinions on this matter... I guess they don't really need to be stated. I just hate it when it becomes preachy on both sides... people will eat what they want anyways.
