Look at everything he’s done so far:

• Sabotaged public health
• Sabotaged environmental protection
• Sabotaged international relations
• Sabotaged economy and taxation
• Sabotaged internal stability
• Instigated violence with every decision, saying, or act
• Just started another war in the Middle East with Israel as the fulcrum.
• Netenyahu has been offending quite literally the entire world, and recently said “you’re letting the bad guys win” to the EU when they are reluctant to join the war. Not that exact citation but here’s a random one I just found with a quick search: https://en.haberler.com/netanyahu-explaining-why-we-struck-iran-we-are-the-19618702/

Does this seem irrational to you? Well, it’s not if you put on your detective hat and consider them religious nuts trying to bring about the apocalypse by fulfilling the requirements themselves.

Jewish end times:

• God redeems the Jewish people from their captivity that began with the Babylonian captivity, in a new Exodus (Kibbutz Galuyot)
• God returns the Jewish people to the Land of Israel
• God restores the kingly House of David and the Temple in Jerusalem
• God appoints a regent from the House of David (i.e., the Messiah) to lead the Jewish people and the world and usher in the Messianic Age, which is characterised by justice, righteousness, and peace
• All the gentile nations recognize Israel's God as the only true God and gather to the Mount Zion
• God resurrects the dead and judges all souls (and sends some for a year to Gehinnom)
• God creates a new Heaven and new Earth

Christianity: There are multiple passages in the Bible, both Old and New Testaments, which speak of a time of terrible tribulation such as has never been known, a time of natural and human-made disasters on an awesome scale. Jesus said that at the time of his coming, "There will be great tribulation, such as has not been since the beginning of the world to this time, no, nor ever will be. And unless those days were shortened, no flesh would be saved; but for the elect's sake, those days will be shortened." [Matt 24:21–22]

Islam: (Sunni and Shia versions differ on some details, because Shia belief centres on “The Mehdi” character)

1. A huge black cloud of smoke (dukhan) will cover the earth.[note 3]
2. Three sinkings of the earth, one in the East.[note 3]
3. One sinking of the earth in the West.[note 3]
4. One sinking of the earth in Arabia.[note 3]
5. The false messiah—anti-Christ, Masih ad-Dajjal—shall appear with great powers as a one-eyed man with his right eye blind and deformed like a grape. Although believers will not be deceived, he will claim to be God, to hold the keys to heaven and hell, and will lead many astray.[82] In reality, his heaven is hell, and his hell is heaven. The Dajjal will be followed by seventy thousand Jews of Isfahan wearing Persian shawls.[note 4]
6. The return of Isa (Jesus), from the fourth sky, to kill Dajjal.[83]
7. Ya'jooj and Ma'jooj (Gog and Magog), a Japhetic tribe of vicious beings who had been imprisoned by Dhul-Qarnayn, will break out. They will ravage the earth, drink all the water of Lake Tiberias, and kill all believers in their way. Isa, Imam Al-Mahdi, and the believers with them will go to the top of a mountain and pray for the destruction of Gog and Magog. God eventually will send disease and worms to wipe them out.[note 5][84]
8. The sun will rise from the West.[85][86][87]
9. The Dabbat al-ard, or Beast of the Earth, will come out of the ground to talk to people.[note 6]
10. The second blow of the trumpet will be sounded, the dead will return to life, and a fire will come out of Yemen that shall gather all to Mahshar Al Qiy'amah (The Gathering for Judgment).[88]

Now look at these as allegories. How would a group of zealots interpret them?

Not having sex doesn't make incels believe what they believe, believing/acting like that makes them not have sex. A lot of them don't just feel they're owed sex, they feel they're owed devotion. The fact that the prostitute doesn't actually like them and will only spend time with them the amount they're being paid will become a problem in their eyes.

And beyond that, the reason the hug helped this man is that it was genuine human connection. It was an act of free sharing in a way that Graeber would describe as an interaction of communism rather than exchange. Giving from one who has to one who needs simply because it's needed and easy to give. A prostitute is sex as an exchange, which includes both parties able to walk away as though nothing happened (indeed, the old saying goes that you pay the prostitute to walk away just as much as for the sex). Hell, many incels scoff at therapy because of its nature as an exchange. What they seem to lack is genuine constructive community, and often also the ability to actually partake in one appropriately.

Also I feel like it might result in a prostitute doing a mass shooting, but I can't defend that suspicion
