Focusing on your male/female muscle example.
Do you think being politically correct requires denial of the fact that men typically have higher muscle mass than women?
I very much doubt you will find anyone here who would deny that fact and yet there are many people here (myself probably included) who you label as 'politically correct'. How do you reconcile that?
I think you don't really understand political correctness and that you are railing against a straw man.
The 'politically correct' don't deny that men have greater muscle mass than women, they just object to the notion that this is any reason at all to deem women as inferior to men generally.
Anyway - As you almost certainly have lower muscle mass than I do I suggest you leave this discussion to the big boys and don't worry your pretty little head about such matters.
