"The entire population" doesn’t want to eat only beef and drink milk, however those are way more subsidized than other food. The real winners are food mega corps and a few rich farmers.

Remove the targeted subsidies and "the entire population" will eat less meat and more peas. Subsidize the peas and not the meat and you’ll see vegans skyrocket.

While the entire population externalises the negative effects of their diet on the rest of the world. If you’d sit alone on that branch you’re sawing off, I’d say good riddance! But unfortunately, you’re destroying this marvellous spaceship we all depend on, just for a little convenience.

True. People would have said the same in defence of colonialism, slavery, genocide etc.

Generations later it's easy to look back and say "of course that stuff was bad, I would have fought against it too".
