Even trans people aren’t beating the “nearly all mass shooters are men” statistic.

Well, that’s a completely different argument.

If something is wrong, then it’s wrong, regardless of how efficient or inefficient it is.

How much earlier are we talking? I bet if you asked prehistoric hunter-gatherers whether they thought animals experienced pain, they woulds say yes. The idea that animals were automata comes from Descartes.

How about I just get to eat meat because I consider it far more humane to be more efficient about proteins?

What does this have to do with anything? This is bringing efficiency to an ethics fight.
