This isn't complicated. Many vegans would prefer to never eat where meat is being served, but recognize the practical reality that if you want business to start providing more ethical alternatives, you need to actually patronize those businesses. So they compromise by providing that revenue, while still trying to avoiding cross-contaminating what they're eating with what they see as murder-byproducts.

So I don't disagree with anything in this statement, but what is it about cross-contaminating that's an issue here specifically? Is there a health reason to avoid any intake of meat products or an ethical/moral one?

For the later case... I'm on board with sane things (don't fry veggie burgers in animal fat) but less with (don't prepare this food where meat products were prepared) simply because... I feel like the same amount of effort should be taken with each meal and vegetarians shouldn't require separate processing things.

To draw a parallel, I'm lactose intolerant myself, but I've always felt it's a bit silly that <GENERIC COFFEE PLACE> has separate blenders for milk/soy/other (except almond, due to the factor of nut allergies).
