nah, i hate people who treat their diet like a religion and try to attach a morality to it.
Plants are living things just like animals, just because one is cuter and more cuddly then the other doesn't mean you are doing something good.
Even the people that come from the environmental angle don't realize that both ways leave footprints that can damage the environment. Organic veggie farms are not very widespread compare to dairy farms and meat harvesting plants, meaning more fossil fuels are burned shipping around the nation. Nobody advocates eating locally made produce though,
The solutions are often more complicated than just being vegan or not.
