Men usually think very straightforward. So the idea of a female friends might seem pointless to some guys, since "you're giving your attention away for free and getting nothing in return".

This mindset already assumes that if you don't receive sex from women, they're not worth your time. Which is absolutely false, and totally leads to an eventual lack of understanding between the genders.

Women really CAN be your friends, and NOT just use you as a "shoulder to cry on". Understanding that there are women in your hobbies, your job, communities you reside in, is crucial to understanding women are human beings just like the men around you...

The dehumanization of women was a long lasting thing that men these days have to rid from their minds. In order not to look at them as these sex dispensers.
