No, but donnie dumbass thinks he is, or thinks he can convince his listeners he is, and of course being vegan (or "vagan" as donnie says) is just axiomatically feminine.

As if women don't eat meat? I mean the whole narrative around meat-eating and masculinity is just so fucking stupid. Even the most hyper-feminine of women and the most weakest of males can....order something with meat in it? Hell, I've noticed people in the hospital being given trays of food that had some element of meat in it - somehow these people at some of their weakest moments managed to....eat meat.

I just have no idea where this stupid idea even came from that if some male abstains from eating meat that they are feminine? The male dumbasses (and the females that prop this stuff up and, oh, they exist) who talk like this all act like they really did something bigly masculine to...purchase meat? And then chew it up? I always ask them if they know women who eat meat, and of course the answer is yes. I ask them if those women are in danger of growing a dong.

I chalk it up to advertising.
