Not all Red Ajah are misandrists. Jordan said that not all members of the Red Ajah are rabid men-haters, but pointed out that they will tend to develop a dislike/distrust for men as part of their job. To be Red Ajah means that your primary mission is to capture and gentle channeling males, so all men become potential enemies. After having this outlook for several decades, it will be hard to have a normal relationship with men.
My Comment: Something that I would personally like to add to this discussion is that all Aes Sedai believe in the importance of stopping male channelers, but the Reds are those who consider it more important than anything else they can do with their talents. This will tend to attract women who dislike men.
