Vegan ≠ Vegetarian.
Veganism starts and ends with “no animal exploitation”. And due to some weird ingroup/outgroup dynamics Extremely Online Vegans will get batshit insane radical with it and refuse to feed meat to their cats or insist that eating honey is fundamentally unethical.
I eat very little meat, mostly for environmental and partly for ethical reasons, but bringing up the environmentalist side of vegetarianism to defend veganism (a radical dogma based on a specific ethical stance) is missing the mark entirely.
With all that said, everyone should eat less meat, and way less red meat.
We’re like 1960s tobacco industry at best. I don’t see the subsidies on red meat going away in the next 10 years, and probably not the next 20 if I’m honest, short of a catastrophic food crisis that would cause us to re-evaluate the number of human calories produced per hectare of agricultural land.
I’d like to be wrong, and change does come in waves so maybe 10 years from now I’ll change my mind. Maybe. But right now the idea of not subsidizing red meat production is fringe even within the left of the left – and the left hasn’t exactly been making electoral strides in most countries recently.
