That seems like a very blanket statement to make about an entire group of people. I’m not vegan, btw. The vegans I know make that choice entirely independently for the sake of the environment, because they hate the conditions in factory farming, or any number of other totally reasonable reasons. They aren’t forcing it on anyone else, or their pets for that matter. What makes you feel this way? They seem reasonable to me, even if I have no problem personally with drinking milk or eating eggs.
