I mean there's no health advantage in worrying about rennet in your cheese.
We eat vegetarian up to twice a week, partly for health, partly because it's cheaper.

I used to know a vegan, he was strict about what he'd buy for himself but wasn't that fussed about cross-contamination and the like, which I thought was fair enough.
