Why are so many vegans militant about veganism?
I have a couple of Facebook friends who are vegan. I am happy for them (and my vegetarian friends). I sometimes eat vegetarian myself.
But they are not content just to be vegan. They are constantly proselytizing. Posting animal horror things in my newsfeed. Constantly posting recipes and promoting vegetarian or vegan lifetstyles.
Why do I care what they eat, or why do they care what I eat?
