No, not because they cannot abide seeing carnivores in action.
But because the program in question depicts consumption of a meat dish the vegetarian used to love before swearing off animal flesh.
I guess if one truly is dedicated to his or her voluntary dietary restriction, watching people chow down on steaks or pork chops should not be all that enticing.
But there's temptation and then there's temptation. I was rewatching a couple episodes of "House of Cards" the other night and Frank Underwood repeatedly going down on those ribs made me wonder.
