I feel like saying "Because she's an independent woman!" is degrading to women.
It's like a person standing up for me saying "Because he's not a dickless twink punk that you can push around".
I mean, why put it out there? Why would she need to affirm a person was independent. It should be implied by her very existence, as well as the law, common sense, etc.
IMO, too much support/assistance/reinforcement will introduce things that don't need to be intro'd. Imagine if you opened the door angrily and your woman said "But I didn't fucck him!" in reaction. Ummm sooo is there something you do want to tell me?
