Thinking and beliefs such as women are meant to do all the house work, marriages are only between a man and a woman, etc are outdated.
They are archaic.
And often unproductive and harmful.
As times change, so do things.
Usually for good reasons.
Old ways of doing things don’t always stick, especially when they are flawed and ineffective belief systems.
If you want to keep up, you need to change too.
And update your belief system
You can’t insist on an outdated way of thinking to be the norm when it is already outdated.
That’s one of the things that causes social discord.
And such behaviour only causes you confusion.
Makes your, and others lives harder – for no good reason.
You either keep up.
Or you become obsolete.
