The dictionary definition of emasculated is "(of a man) deprived of his male role or identity." or "made weaker or less effective"
So, I'm a guy, and I'm not entirely sure what it means to be deprived of a man's role or identity. Does it mean to not feel manly? Does this word have to do with gender norms? The reason I thought the word was sexist is because it says "man's role".
I found a sentence example saying, "He was worried his pink pants would emasculate him a bit, but he wore them anyway." See it seems like it's talking about gender roles.
