Very eager to read your thoughts here, but here's what immediately comes to mind, already at the intro:

What about sex workers? Sex workers provide a valuable service. People claiming the label "incel" are apparently forgetting that they can hire sexual services. (Unless they are also too broke to do this.)

Granted, I'm not saying they should or shouldn't. I believe it's totally their prerogative whether or not they are interested in purchasing sexual services. But claiming that you are "involuntarily" not having sex — i.e., that your not-sex-having is "forced" upon you — when you DO have the option of purchasing sex, is also seriously misguided. These guys seem very oblivious to that...
