It seems like you're saying "yeah you're a girly man, that's what you are now, better learn to embrace it" rather than "learn to express yourself how you want".
It's true, I am saying that. I think the root problem is how the parent comment author is being treated, rather than how he is acting, since his main motivation for changing how he acts is to be treated differently.
He's free to reject my advice, but I know that when I was a younger person going through the same thing, it was exactly this advice that helped me survive after many years of only being ineffectively told that I needed to "man up."
