You also misunderstand what a contradiction is and how it differs from a logical contradiction. Don't mind me if I go out on a limb about the implications of your words if you don't even know basic commie jargon while calling yourself commie on a commie site.

We don't even need to reach into theory to define this as a contradiction. Here is their comment further up the thread.

one can eat meat and not want animals to be abused.

This is true (many people do both of these things, as many people do many contradictory things), but it's obviously contradictory to not want animals to be abused while buying products of animal abuse. That's it, that's the entire argument here. The position that they're defending is that there is no contradiction of any kind there, which is ridiculous. I think this person is just trying to cause arguments so they can pick them apart to try to cause more, as @onoira@lemmy.dbzer0.com said.
