Quick additional note on your last bit for 1- you're really kind of proving my point about individual behavioral/consumer level change acting as a release valve (though you admit it's subjective). There is no way forward on climate that isn't structural and doesn't hold powerful organizations to account. That doesn't happen through the true believers opting out. Or put another way, it is ethical to not eat meat and it relieves guilt, but the political goal should be to make it harder to eat meat and even remove it as an option.
