This is a quite remarkable consensus among philosophically-minded folks.  I will be interested to see whether it holds for other issues.  (By the way, a version of the last choice has been defended by Loren Lomasky [Virginia].  In general, it's clear that many philosophers are quite ready to dismiss the cultural and culinary traditions of hundreds of millions of people as having no moral weight.  In this paper, I speculate about the likely practical limits of these moral arguments for vegetarianism.)
