I don’t think you understand what class warfare is.
The fact that it’s co-opted by rich people as trying to convince you that environmental disasters they cause is your problem doesn’t change any points made by actual vegans, or the fact that it’s far far cheaper. Even with all the subsidies given out, a pound of black beans/lentils has more calories/protein than a pound of beef, and will cost 1/5 the price. Sure if I want to splurge and buy a premade veggie burger it’s more expensive, but generally it’s just way more affordable.
