You may not be wrong overall, when it comes to systemic issues. The problem men have in this context is systemic and societal. The problem women had historically with inequality and lack of liberties was also systemic and societal. Men not adapting to fairness and equality though, that may be societal but it isn't systemic, as in an issue caused by some social system. It maybe a psychological issue that has reached epidemic levels and maybe it can be addressed systemically, but the cause boils down to individuals not accepting a just and fair outcome.

This also applies in other matters like race relations for example. People whom historically have been afforded better opportunities suffer when people from all races are treated fairly. That is what justice looks like. Not having an unfair and unjust entitlement does not translate to suffering from a systemic issue. Accepting just and fair outcomes and adapting to a current reality is a healthy way of adapting.

The reason I feel strongly about this is because historically, when groups of people have a social complaint and they feel wronged and their entitlements taken away from them, they tend to turn to violence or some other social harm. They end up implementing injustice at mass scale. For example, regardless of your views on the topic, abortion laws in America today are designed to degrade liberties of women (regardless of anyone's intent). Fairness and equality to all members of society is not a systemic issue that needs correction. Failing to obtain a romantic partner of interest is not an unfair situation, for men or for women alike.
