The term 'incel' in its usage and connotations is fairly nebulous. In strict definition of the term, there probably exist around hundreds of millions of incels out there. In stark contrast, incel communities themselves represent a much smaller number.
Being an 'incel' nowadays has come to mean that you accept a certain set of axioms, that you belong to a particular internet sub-culture and that the customs, language, attitudes and values of that culture are a major part of your own self-identity.
It's far divorced from the original hopes and aspirations of those by whom the term was first conceived. Alana would be distressed at what discourse relating to involuntary celibacy and love-shy individuals has now morphed into.
