Look into support groups for stay at home dads if you think they no longer apply. They do. Likewise, men still get the raw end in custody because of gender stereotypes and norms.
You will always find cases where examples of sexism, racism, bigotry, and many other types of unfairness still exist, but that’s not because those things are accepted by mainstream society, it’s because there are still places where people with outdated unfair ideas that goes against mainstream society are still holding positions of power and use their power to spread their unfair views.

This stuff al being based on thoughts and feelings and social consensus makes none of it meaningless. To the contrary it's a part of what makes being humans so profound and amazing. We do stuff like this, amd we don't even generally ever think about it. How is tjat meaningless?
Imagine an imaginary tool called a “widget” where everybody had a different view of what a widget actually is. Some think it is a screw driver, some think it’s a wrench, some think it is a hammer, etc. etc. Now imagine I asked you to go to my tool box and hand me a widget. You would have no idea what I am asking for because the term widget is a meaningless description for a tool; agree?
