Agreed. I've been a vegan for 14 years, and by far the absolute hardest thing about being vegan is dealing with the social consequences. It has got better recently, but people can be so nasty, judgmental, argumentative, unaccommodating, and will happily accuse vegans of all of the above while inflicting these very behaviours on us. Even when they are not being deliberately nasty, they will do things like telling us to "live a little" as if veganism is unpleasant, and shaming for not joining in eating animal products, blaming us for their own lack of accommodations.
This is a long way of saying that there is no way that Jack is tough enough to withstand the social consequences of being vegan, even if she was interested. Unlike me, she would have had the added pressure of being part of woke circles, where veganism is unpopular and shamed as being for the privileged.
