Well, meat requires more plants to “suffer” than eating the plants directly. So if this was your line if reasoning, you would be a staunch vegan. The majority of crops are grown to feed livestock.

People usually make your argument in bad faith because even when corrected you never had a moral interest in “minimizing plant suffering” to begin with. You just thought you had a good gotcha.

> So if this was your line if reasoning, you would be a staunch vegan.

Not really. A person who eats both doesn't typically agonize over the morality of eating animals or plants like many vegans do. It's pointing out the fallacy of advocating veganism on the basis of animal suffering.

That of course is only one argument for veganism among many much stronger ones, but it doesn't make it a bad argument to make.
