There is no single, overarching, "incel community". "Incel", isn't a single community any more than, for example, trans people are a single community.
You may argue incels are a class of people, as you can arrange anyone into a theoretical class, but incels are not an organization. Incels are simply anyone who can't get laid despite approaching a wide variety of people.
Virgin shaming by media
The media often disingenously tries to paint all hard up men people as a terroristic singular community, by capitalizing "incel", as, "Incel", outside the start of a sentence or pretending incel is an acronym like, "INCEL", to take advantage the fact that the word' "incel", is accidentally linguistically similar to the word, "ISIS", to provoke fear of involuntary virgins. Essentially a sophisticated form of involuntary virgin shaming.
