If they all got their own private sex dolls and stuck with that I'd be all for it. Why can't they stick with that though? They see women as nothing but sex dolls so why not just buy a sex doll and be done with that, leave everyone else in peace.
Thing is for whatever reason (depending on the incel) I doubt they'd be content with a sex doll. They'd want it to have a soul just so they can crush it, which is why they're pissy at women out there. These strange creatures that give them boners have minds and will of their own, and they don't know how to deal with that or their boners. They need to learn self control and to respect other people's autonomy and get the self awareness to treat others how they want to be treated, and not to judge others lest they be judged.
