“I’m more of a traditional woman and I expect men to pay me for things” is an acceptable argument in society.

“I’m a traditional man and I don’t like it if a woman makes decisions in the house” is considered an unacceptable one

“Women have the instinct to want to be with men who provide and thus it’s normal to want to be with rich men” is an acceptable argument in society

“Men have an instinct to primarily look for sex and so it’s okay to only talk to women for the purposes of sex” is considered an unacceptable argument

I can go on and on. You can’t just use traditionalism whenever it suits you and completely disregard it when it doesn’t. Same goes for arguments when it comes to biology
