Here’s a simple one. When a lady enters the room, stand-up. It’s polite, it’s charming, and it’s a small point of etiquette that’s being lost.
But Grown Man, women want equity! Why should we treat them any different from men?
Because you can’t procreate with those men. Women get unique rules because they have unique plumbing. You treat them different (better) because they are different (better).
There you go, that’s all I’ve got.
