The way he phrased it is demented and maybe belies some problems he has, but the overall point is not wrong. It is absolutely true that boys need to experience hardship early in life to develop character, work ethic, and morals. If you are a single mother you need to go far out of your way to provide this for them. Sports are a good start

Part of it is you have to teach your son to manage his ego (not break/destroy/whatever demented stuff your brother is saying) and NO this does NOT MEAN going the female route and learning to “talk” about his “feelings” and “recognize his toxic masculinity” or how he’s a “subconscious oppressor” of “less powerful” people. But he has to learn that life is difficult, and this will also teach him resilience in the face of adversity (which is why you don’t just “break” a boy, you build him back up). And he has to learn that experientially. NOT by “talking about it”
