I was just planning a dinner party a while ago and the Venn diagram of what foods I could make was truly vexing.
I will move heaven and earth and scrub pots and pans for someone with Celiac, but working around people’s mere preferences is irritating.
prior generations would just eat around it or suck it up.
My friend circle in our old city included both Falstaffian omnivores and vegans, and we entertained often. It's not hard to ensure there's food available for folks on a more restrictive diet, and even my friends with UCI racing licenses generally ate like normal people at social events.
Mileage varies, obviously.
(I will say, however, that after having made a vegan "bolognese" once, I have no need to do so again. It was much more effort than the already time-consuming genuine article.)
