Could this be because men who do these things are actually real men who are unconcerned with proving themselves to other men?
We might might differ about the definition of a real man, but that's another debate.
What I notice, is that modern women become more and more masculine and modern men become more and more feminine. This trend is supported by the media, politics and activists. JD seems a typical product of this ideal.
I believe that certain ideas of equality between men and women are serious misconceptions. Don't get me wrong, I believe in equal rights and personal freedom, but there
are biological differences between men and women, both physical and mental.
Sorry for the seriousness, but I hope you understand my point.
