Let's set aside the enormous debate that could be had around whether or not killing an animal "humanely" is ever actually possible, and instead assume it is for the sake of argument. Do you think that the person who originally stated that they want to consume animal products while also minimizing animal welfare is _actually_ going through the effort to ensure any animal product they consume was suffering-free? That means the milk powder in the crackers they had at lunch were _verified_ by the OP to have not involved any suffering on behalf of the cow who yielded the milk, or the calf who was born to consume that milk. Do you think that is what happening, and that the OP is _actually_ making sure they only meat from animals who grew up in a grassy field and were killed instantly with 0 pain? I don't. And if you also think that seems unlikely, then I think you should agree with me instead that perhaps we can't really be claiming to value minimizing the suffering of animals while consuming their bodies.
