It’s good that you mindfully reduce meat intake and at least think about it, and I’m not trying to force you to do anything, but the logic here doesn’t follow. You could equally say “everything in this world has nuance and can never be binary (so this can’t be binary)”.
Do you know the idea of a kind slavemaster? Namely: if someone told me they only buy products of slavery if they’re made by slaves with kind masters, I’d be a bit baffled and I’d say “but it’s still slavery isn’t it?” There’s basically nothing worse you can do for something’s welfare than having it destroyed, no? Barring edge cases where you’re putting something out of its misery (definitely not the case when making animals into hamburgers).
