I have a theory that everyone goes through the same stages in a relationship. Initially, you are desperate for any affection at all. Next, you try and get affection from those you find physically attractive. Finally, you try and get affection from those who you truly synchronize with. Everyone, regardless of gender or sexuality, goes through these stages in a relationship.

However, women have a headstart. This is because in our society, women tend to be given affection and intimacy from their peers and their friends(again this is just on average). Whereas men are not given this affection or intimacy from their peers or their friends and they are told by society that the only places to get affection are from their parents and their SOs. This combined with the fact that there are 2x as many abusive mothers than there are fathers (https://childprotectionresource.online/mothers-are-more-likely-to-abuse-children-than-fathers-fact/) means that women are on average given a headstart when it comes to this stuff than men. This leads to MASSIVE amounts of redpill/simps/nice guys.

Because of this, red pill men also say that a woman can get laid regardless of how she looks. This is projection. Red pill men will try to have sex with any woman due to the fact that they have struggled with getting any affection their whole lives. When they say that a woman can get laid regardless of how she looks, what they really mean is that she can get laid by red pill men regardless of how she looks. No one, regardless of gender in my opinion, will want to have sex with a red pilled man so this is why red pilled men are right and horribly wrong at the same time.

This is also why red pilled men believe in the "cock carousel/AF/BB". They believe everyone is as emotionally stunted as them, and they assume the worst. This is generally not true regardless of gender. In other words, this is just projection.

This also explains why men want sex more than women. Men do have higher libidos on average than women. However, if most men really only wanted sex for the physical pleasure, they would just jack off and forget about it. What men really want is the intimacy that comes with sex. They want to be with someone who loves them, something that has probably never happened to them ever.

So what does this mean? This means that red pilled men value intimacy and emotion more than you think. If you want to stop your brother, your son, your male platonic friend, your bf, your husband, etc. from falling into the red pill, the most important thing to do is to hug them and show them affection and intimacy. Tell them it is ok to show their friends their emotions and affection as well. Only then can we truly stop the red pill movement for good.

TL;DR: A lot of red pill beliefs come from the fact that red pilled men are emotionally stunted. Men in general get no affection from anyone aside from their parents and their SOs. Red pilled men have experienced this worse than anyone else. To stop men that you know from falling into the red pill, compliment them and show them affection before it is too late.
