I'd love to see what you're basing that conclusion on. Most American women identify as feminist, which aims to liberate men as it does women from deeply entrenched gender norms. Less men identify as feminist, and one could argue some of that loss is because some men don't value the liberation of women while still valuing the liberation of men. Admittedly, not all feminists are working towards liberation equally, but at its core it's about self determination for everyone regardless of sex or gender. Most marriages in my social circle have the woman earning more than the man, and the men are not operating as "sentries" or "sex toys" in these relationships. Most do not need a male protector at this point and can certainly get sexual gratification solo or elsewhere if something happened. If you're not American I can't really speak about your country, and even in America lived experience can differ, but it seems reductionist to say nobody cares about men.

It seems like you have an interest in crypto, which is fine, but that community seems to self select for a certain type of person. It's possible you're just not in spaces where the majority of people behave the way the general population does.
