But then you’re still causing plants pain by farming and eating them. Isn’t that argument no different than saying if you believe that harming animals causes them pain, you should be in favor of eating the ones that are hunted because farming them causes more pain?

If you insist on animal abuse then you should do it through hunting rather than factory farming precisely because of the diminished amount of suffering caused. But it’s still more suffering than would be caused by just eating plants so I’m not sure I understand your point

If you actually believe harming plants causes them pain and that that is bad, you should be vegan. Animal agriculture harms far, far more plants than any plant agriculture ever could.

Not only do you jump to an insane straw man.

It wasn’t an insane strawman though? It was literally the argument they made. Something has to die for you to eat, therefore it doesn’t matter how many things you kill or how necessary those deaths are. The fact that you must kill something absolves you of any guilt for any amount of killing, is the ridiculous argument the person made (and which carnists often make) which we are making fun of for being obviously evil and wrong.
