I don't mind people having an opinion, but when they try and shove that feeling down other people's throats? Thats when I have a problem. I wouldn't mind vegans so much if they didn't try and tell everyone to believe what they believe.
That's because the vegans you choose to expose yourself to are the extremists. I don't understand how you people don't get that you can't have an intelligent conversation with an opposing viewpoint if you spread your political message through echo chambers.
