I don't think anyone is trying to say we can make it "safe" for everybody. I think the point is to have enough variety that most everybody can find something that works.
And by the way-- how many of you "why bother" posters have actually hosted a Mudcat Gathering, or brought something to share, to one? Guess what. A lot of people don't bring anything to share at all. If no one else brought anything, or the host didn't roll out some grub, there'd be no eats.
