When men refuse to view women as possible friends, you’re just showing that you see women as “different” and non people. Would you turn down making more male friends because you want to concentrate on dating? Probably not. If you’re not willing to get to know women as people first, why should a woman want to be in a relationship with you? If you’re not dating a woman anyway, why not fill your time with making more friends? Maybe some of those female friends would become more after a while. Maybe those female friends could hook you up with one of their friends. Women are people who are just as capable of being good friends as men. Maybe better.
