A real man isn't one who punches down, it's one who extends an open hand.
A bit off topic, but I get annoyed when I see statements like this because it always comes from the same type of people who whine about the patriarchy and get mad when someone talks about being a "proper" woman.
You can't be against sexism when you yourself are sexist. Masculinity isn't defined by your subjective beliefs. Stop trying to shame men for who they are because of your misguided personal standard. There's no such thing as a "real" man because all men are real.
