I guess it comes down to environment. Could a "feminine male" really compete against a "masculine man" outside of a synthetically created environment when it comes to safety, or acquisition of resources or women? Outside of that embryo there's no benefit to having "feminine males" in your camp minus intelligence (which they would have to have because they couldn't compete physically).
Ask yourself breh, if society fell tomorrow, who would you rather have on your team...a Wesley Snipes or Justin Beiber?
So you could say it's a social construct, but you can't disregard the biological aspect either. What woman would take a weak man over a strong one? A short one over a tall one? They wouldn't. Only in an artificially created environment can those factors be discarded for a new definition.
Nature doesn't tolerate weakness...never has, never will. Female mammals in nature seek to mate with the strongest most dominant never the weakest.
