Something being normal doesn’t make it right. Obesity is normal. Shoplifting has become normal in many places. People getting drunk is normal. Normalcy doesn’t equal moral rectitude.

Why do the opinions of my ancestors bear on that, and which ones are you talking about? Most of the ones I can think of, unless you run back to the days of tribal europe, would see the culture today as hideously liberalized. Regardless a lot of my ancestors probably did a lot of things I don’t think are right. Heck, I’ve done plenty of things I don’t think are right. None of that effects what actually is and isn’t morally good.

If I’m not running around telling off couples who leave the bar together, what do you care?
