I don't think anyone here is trying to bash vegetarians as a group. I respect every person's right to eat in any manner they choose and for whatever reason they chose it, whether it be low carb, low fat, vegetarian or just the good 'ol American junk food diet and it is possible, BTW, to follow a low carb lifestyle as a vegetarian.
I do, however, have a major problem with PCRM's tactics and fanaticism. Chosing to eat animal flesh does not make me morally inferior to the person who chooses not to as much as PCRM would like to suggest otherwise.
