I fear incels will need to be careful in future. Normies always work themselves into hysterics following a tragedy and start pogroms against the sort of people they hold accountable. After Columbine it was kids who played FPS games or listened to the "wrong" kind of music. After the Charleston church shooting it was kids who posted memes about Rhodesia or collected Rhodesian merch. After the OK City bombing, it was anyone critical of the federal government.
Now it'll be incels who are targeted, or anyone who fits the incel descriptor: unattractive, lonely men. Be prepared, guys. Be ready to defend yourselves, because like it or not more and more people will begin viewing you as a threat. And while the reaction of most people to a threat is to run the other way, some will confront you. They'll try to push you down for holding your head high and daring to walk on their side of the street, and you have to be ready to tell them "fuck off, this is MY street".
If you can, get a pistol for self-defense. If you can't, get a good knife or a decent less-lethal alternative: a stun gun, bear mace, a truncheon, anything. Learn some martial arts, or at the very least learn to throw a good punch without hurting yourself. Never go looking for a fight, but if a fight comes to you be ready to wreck their shit. Show them you're not afraid.
