Some vegans just really screw it up for everyone else.
I commented online at a video where they had blocked a farmer from entering his own farm and he hit one of them. I was about to comment my disgust at this assault but state that it’s a non-peaceful protest to prevent someone going home/to work, when I saw the “vegan group” had replied to a man’s comment...
His comment was the usual “you shouldn’t have been in the road” and their reply was “how would you feel if someone had chopped up and eaten Dexter”
Confused about the reply I clicked on the guys profile to find that his cover photo was his much-loved, deceased dog ‘Dexter’. I was absolutely horrified at their response and made my opinion clear (that this is not how you put a valid argument across, ever)
Their response to me? “Well clearly YOU would like it! Horrible you”
I’m fucking vegan 
This was a well-known “professional” page/group... honestly some vegans just act like uninformed children (the same as any other people in the world) and it tarnishes the rest of us. I don’t tell anyone I’m vegan unless it’s when eating out and that would be to the chef/waiter
