Feminism isn’t just about women; it’s about everybody. You mention a macho upbringing - that’s one of the many things that feminism is trying to fight. Telling boys that they have to be “strong,” be the breadwinner, can’t have emotions - these things are actively harmful to the boys. Everyone needs feminism - it’s about letting everyone be anything.

You may have heard the term “toxic masculinity” at some point. If not, I recommend doing some reading on it.
