The linked post for example, what exactly is that supposed to do? kleinbl00 isn't going to stop eating meat because you showed him a MS paint protester, I doubt anyone would(Maybe you were joking, and I'm just stupid). If anything you're giving veganism a bad name and preventing people from changing to a vegan diet because they don't want to be ridiculed or called a hippie. The conspiracy theorist in me thinks it's not unlikely you're employed by meat companies to eliminate vegans. :PYou find yourself being shouted at, being called an extremist, a hippie, irresponsible, a snob, stupid, retarded, judgemental, a weirdo, and accused of forcing your views on others. Simply because you chose not to harm other beings, you find yourself.
Do you mean that happens as a result of being vegan? I wouldn't say 'simply', I'm vegan and have not once been called any of those things seriously, ever. Clearly there's something else you're doing, probably things like this. I respect you for going to great efforts to make the world a better place, the world needs more of that. But your method is pretty questionable.
