I've also met a number of vegans who won't eat food cooked in or on surfaces that have previously been in contact with non vegan food.  Is there a legitimate physical reason for this behavior or is it just more sanctimony?

It's just sanctimonious. Once a pan is cleaned, there is no meat on it  it's just (yet another) opportunity to push the agenda.

Source: had a vegan flatmate. Tried to make an issue of not using pans that had previously been used to cook meat. They were my pans, in my house (I held the lease). Sheer fuckery.
