My other favorite is that veganism is for white people.
People love to call veganism ‘privileged,’ while conveniently ignoring the fact that the only reason animal products are even close to being accessible for the average consumer is because they’re factory farmed, slaughtered and packed by grossly underpaid labourers working in dangerous conditions, and then massively subsidised by all of our taxes.
I'd imagine many people who call veganism "white" are taking a more global perspective. While factory farmed/processed food is the norm in the U.S. et. al., it's not that way around the world. There are other parts of the world where people attempting veganism would suffer ill effects and even death due to B12 deficiency as not everyone has a wide variety of food to choose from, can go to the store and get B12 supplements, or buy fortified processed foods.
Then, the whole reason the average, modern (U.S.) citizen (or people from similarly set up countries) consumes factory foods in the first place at all is because we're born into grossly overpopulated capitalist societies that can only be supplied by factory farmed foods made possible by fossil energy.
This tweet then uses the unfortunate consequences of human overpopulation + capitalism and it's reliance on factory farms to feed such massive numbers to imply that eating meat is the problem.
Eating meat is not wrong, it is what our species has evolved to do, it's what many other animals do. What's wrong is the way modern humans live, exploiting nature for profit and growing to massive numbers to facilitate capitalism's extraction of natural resources.
Factory farming is very much a global problem that's not limited to the US
We estimate that over 90% of farmed animals globally are living in factory farms at present. This includes an estimated 74% of farmed land animals (vertebrates only) and virtually all farmed fish.[1]
It's not just more people that's caused factory farming. It's increase per capita consumption. The rates of per capita consumption are enormously different. If everyone ate like Americans, we would need 137% of the world's habitable land which includes forests, urban areas, arable and non-arable land, etc. Cutting down every forest wouldn't even be enough
