A lot of leftists are marxist-leninist, anti-sexist, LGBT+ and anti-racist. BUT, they'll tell you the dumbest right-wing arguments to justify eating animals. I get that people aren't ideal, but when you are the urban middle class of the West, there's no excuse to not be vegan. Absolutely, no, excuse, to, murder, animals. Historical materialism lets me ok people from poor/oppressed backgrounds being carnist. I would never denounce a carnist in Gaza, but the Westerners have no any excuses to abuse animals.
I get that some people just have no will, I know people can be addicted. But at least DON'T BE A JERK to vegans. Some "leftists" post propaganda about veganism like YT videos that are literally funded by oil corporations. Some "leftists" are so toxic I'd rather have a conservative as my roommate than them.
The "leftists" lie all the time. Meat, dairy, eggs and honey are luxury products available mosty to those in the imperial core. The poor countries like India, Nigeria, Uganda and North Korea eat diets closest to veganism BECAUSE plant foods are the cheapest foods, not carnist subsidized McFood.
Dealing with leftists, especially online, is draining to me. How can I be productive as a leftist and not go insane? How can I cooperate with carnists to achieve the revolution? I see no easy solution here
The leftists in my IRL circle are often vegetarian/vegan or trying to be. Some are carnists, but zero do the anti vegan thing. I've had anti vegans come and go. The end up having wrecker sort of personalities. Like what sort of "leftist" would make anti-veganism part of their praxis.
In regards to dealing with them, I'd win the battles when it was easy, but avoid a massive struggle, as our energy is limited. If you're getting in an online battle, don't stress the individuals who debate-bro every point. Just make your point and go, and block the debate bro types. If you meet an anti-vegan leftist IRL, hold back and conserve your energy, as they'll likely get outed as a wrecker sooner or later.
