This is what's missing in the "incel" philosophy. And what is missing in every single person who thinks they are entitled to another person's attention/body/affection. They are not actually entitled to any such thing and the real reason they cannot seem to find anyone to fulfill their needs is 1) that they reduce every woman (usually) to someone whose only role in life is to fulfill their needs and 2) they are total creeps and women can tell.
Look, every single one of us has been between relationships/sex partners at one time or another and if this is not a good thing (sometimes it's good not to be in a relationship - you have more YOU time, which is 100% a good thing), then we usually take the time to figure out why and fix it. Sometimes it's things beyond our control (illness, too much work, family issues occupying all available head space, etc). When it is something in our control, we can and usually do try to take steps to change it. We all have faults and flaws that negatively affect our relationships. And we all also have the power to change it.
But these "incels", in addition to feeling entitled to things they are absolutely not entitled to, are completely toxic, horrible people no one should touch with a 10-foot pole.
No one is entitled to sex. No one.
This argument that sex should be "redistributed" to people who can't get it turns women (in this case) into handmaids. It's just disgusting on the face.
