Wtf is "inherent manliness"?
I fully support your post except for this.
Personally, I think that the idea of this concept of "manliness" or is damaging (even if it's just meant in jest, as it's extremely overdone, and I believe it just serves to perpetuate it). It needs to be let go of and we need to realise that we are all individuals, and all express ourselves in our own ways. There shouldn't be any sort of idea of a role we should be playing, and we should not have to face criticism or be looked down upon if we feel we want to express ourselves differently, perhaps more in line with what society considers "feminine".
Also, I'd hate to be one of those fake men.
