You've been vegan for 19 years but does that mean you haven't had any meat or animal products in those 19 years?
Because from what I understand, most vegans do eat at least some meat and animal products once in a while. "Breaking vegan" they call it. And it's OK to do it as long as you're vegan, otherwise it's not right and you're a murderer.
Because only being vegan is an ethical stance. Where being vegan of course means posting vegan memes on twitter and stuff like that.
