Your word analogy is wrong.

It‘s not eat : rape, it‘s eat: fuck, so for some the equivalent for rape is eating meat or more specific killing animal : rape.

We evolved to eat and we evolved to fuck.

But like sex doesn’t mean rape so does eating not necessarily mean meat or at least no much and not without consideration who the animal is raised before we kill and eat it.

A long time in many societies we didn’t really care what women felt during sex or if they were even willing to.

But we evolved further and learned women have the same rights as men and rape is a bad thing. We even redefined what is considered rape. It’s not that long ago that raping your wife was impossible from a legal point of view.

We also changed our view on factorial farming, at least many of us. At least we want meat from a happy cow that lived on the pasture and not penned up in the barn without sunshine. The next step isn’t that far, no animal should be killed if nutrition is possible otherwise. We already spare some animals as food. In the west it’s cats and dogs, in India cows. And some include all animals in the don‘t eat category.
