At this point I would not be surprised if we started seeing feminist groups becoming armed and violent. And as much as I have a disdain for political violence, I don’t think I could condemn them for doing so.
This is crazy… misguided, hypocritical, extreme, and unsafe. Etc.
but you also just used 2 names in your example… others here already said the right stuff, but I reiterate, it’s a lot of symbolism helping create feelings of unity in a family unit, but also there are legal issues/benefits for changing a last name.
