Christians and Christian morality. They teach men to demonize strength and the (correct) celebration and public praise of strength. They teach men to put women on a pedestal. They teach meekness, pacifism, and getting on your knees to ask higher authorities to make everything good in their lives.

No personal responsibility. No individualism or looking out for yourself - instead self-sacrifice and "noble" sacrificing for others, always a long list of others that must come first.

So men don't look out for themselves or other men. We just get up on the alter to be sacrificed for womens' retirement plans.
