I'm not convinced that's how it's going to play out actually.
Most of the men who initiated this culture change are in their 70s now. A few of the people who set the original legal precedent whilst same sex marriage was illegal are dead now. As is the world that those homophobic men who needed to marry men "as a woman" were in. The world moved on but these men haven't.
It's all passed you by though and you are sucked into their profoundly sexist legacy of a time long gone without even realising it.
Having worked with that generation for many years I know what they are like and it's definitely not feminist!
Yeah we are a bit sneery about it, because we have a lot of years of experience with the men who set this all up and know what they are like, and they deserve a bit of sneering for the dumb number they have pulled.
Caitlyn Jenner, eh? Yes he's a feminist isn't he. Young people must admire that old man, no?
Hahaha.
