Hey, asshole, you've been an idiot the whole time on top of being a huge asshole
The person didn't say "Id go vegan but they're assholes", they said they'd not participate in a community with you dumbasses because of the behaviour people like you participate in
Also your insults suck and make people sound cool as fuck
Not being an asshole to people is the default behaviour, to be dropped when someone breaks the social contract and does not uphold their end
I get that your parents didn't teach you basic manners but that's not our job either. Learn how not to be a bitter piece of shit or be forever considered a perfect and pathetic example of OPs point
My comment poking fun at the ridiculousness of double standard in tone policing got removed for trolling so let me be more explicit:
There were already very rude jokes and comments about vegans in this thread. Rudeness against vegans is the norm and played for laughs, but god forbid a vegan returns the favor then suddenly everyone is crying for more civility.
Also sincerely held beliefs should be communicated sincerely. No ones going to believe the dude that says "I think what you're taking part in is a horrific injustice carried out on an industrial scale but to each their own I guess. Lets agree to disagree."
