Satire or sarcasm? It's hard to tell these days. The first is only so-so, but here's a response to the second:
Everybody is angry at everybody. And I think it is due to misunderstandings, like most human problems.
But yes, incels should do something useful with their lives. Everybody should. Single or not, sitting around hating women isn't doing anybody any good. My impression is it's mostly an excuse to get together with your boys and complain, a time-honored practice. Women do it too.
Men often misunderstand - that word again - what I'm trying to say. Since I try to be quite clear, it's probably some of those intentional misunderstandings.
It's simple: men who can't find a woman need to work harder before they give up. Men are visual, so women use makeup, clothes, etc. to be more attractive.
But women are more complicated because what constitutes attractive is broader, and often very opaque (even to them). So men can't just put on makeup and a pushup bra. But they can take steps to be more appealing. First and foremost, be nicer. Guys are often pretty shitty to women, so don't do that. Girls like boys who bathe regularly and dress well. They like to dance, so guys should learn how. They don't want to be house slaves, so learn how to do housework and look after yourself.
What if a loving man has done everything he can to be more attractive and still can't find a parter? Then he's probably being too selective, since it's about 99.99% likely some woman would have taken chance on him by then.
A-holes and guys who won't make an effort shouldn't complain, but lord do they complain.
