Question for the non-veg people in this group

I've noticed a lot of non-vegans/vegetarians posting and commenting in this group, and I'm curious what your reasons are for participating in the group. Are you here to see if it might be for you, to defend your food choices, to understand our motivations, to troll? Have any of you done research, read books like "whole, Rethinking the Science of Nutrition", or "The China Study", or seen documentaries like "What the Health", "Fed Up", or "Food, Inc"? What is your opinion of those who are vegan?
