A correct version, based on actual trends and how incels are;
Always be rude to an incel, never be nice or flattering or good to him. The incel cheers on murder and harm to his fellow citizens. Shun the incel.
If you know someone is an incel, leave them bad reviews in any business they may have and out them publicly.
Always give anyone who sympathizes with incels the worst reviews - see Jordan Peterson.
Always dislike and report incels and incel supporters on YouTube. The less incels on youtube, the better. The less incels ANYWHERE, the better.
Always criticize and be negative toward the incel. He will cheer at your death. He does not deserve your positivity.
Never follow an incel or incel supporter on the relevant social media sites - always alert those around him to his true, malign nature.
Choose your porn with the Chadliest men, and support the rights of the performers. This angers the incel, because the incel despises open sexuality.
Always support accounts and ads that shit on incels and make fun of them / debunk them.
Never assist a known incel. The incel would not do the same for you, and could end up killing down the line. Do not lend your assistance to the incel. That assistance is wasted on such a lowly, vile, ugly creature.
