Honest question: of all of the things people can do to make the world greener, why is it mostly (a subset) of vegans that look down their nose at other people? You don’t see people driving electric cars pulling up at red lighted and giving people shit for driving an SUV People in middle America don’t come into your city and shit on you for how far food has to drive to get to your ass. People that grow their own food aren’t protesting your grocery stores. Chill out.
