I'm currently dating a feminist. She's pretty vocal about feminist causes but she's still feminine and a very good to me. Whenever she does spout off about feminist stuff I keep my mouth shut and pretty much ignore her until it goes away. The first rule of Red Pill is: Don't talk about the red pill.
How old were these women you approached? I'm going to assume younger. Any woman who has been to college in the past 8 years or so is going to come out indoctrinated to all hell about feminism, feminist courses are required. These women are the equivalent of black pilled or MGTOW men. I have had a few female friends outright ruined by feminism, a pity too since they were very cool and very pretty. Now they are bitter and past the wall.
You can most def bang feminist women, but you have to be immune to any kind of emotional outburst they engage in. Whatever she says, and no matter how stupid it is, you have to just not care and not react. It's not enough to pretend you don't care when you do because your emotions will show in your face, you have to seriously not care at all.
