I hope your message to your son is to help himself and other men, not to fight women for what they have.
For example, male mental health. Loneliness, a lack of relationships, a feeling is being lost, all terrible and epidemics right now. What is it caused by? Men relied on women to be their social secretaries. Now that women are staying single more (because a lot of men are pigs and we don’t need them) and men are favouring hook-up sex from apps, or forming relationships, men are lonelier and more isolated. There’s some statistic that married men describe their wife as their best friend about 60% of the time. Married women 30%. The obvious solution for your son to avoid this is to prioritise being a good friend, making social connections, having a real monogamous relationship not hook-up sex. Being worthy enough for a woman to commit to. Doing things that promote mental health, like volunteering and helping others. Exercising, eating well, having hobbies outside the home, not drinking too much, not taking drugs, not playing too much on electronics. All of that he has power over.
Instead of which some men look at their loneliness, lack of connection, lack of power, lack of educational or job success in the world and think women somehow stole it. And they blame women and hate women for it. Making themselves even less dateable and therefore even more lonely. If you teach him to hate women, he will be lonely and miserable.
