This thread makes clear how flawed the term "incel" actually is.
If an incel is someone who is involuntarily celibate, who wants to fuck but doesn't have any female to fuck, a HUGE part of all high-school and college normies aged 16-22 or so are incels. Even if you add "never had sex before" to the definition, a good deal of college boy normies remain "incel", since many men don't lose their virginity as early as the media (and their bragging) suggests.
/r9k/ has been destroyed by facebook normies who flooded the board and made it all about "18-year-old college normies who currently do not have a girlfriend". The vast majority of adolescents and guys between, say, 16 and 21 or so are a bit socially awkward and often don't have as much success with women. Average = Normal = Normie. A young normie can very well be an incel: don't watch so much TV. There are millions of young normie guys with normie grades, normie friends, normie families, normie interests and so on out there, who want to fuck but don't have a female to fuck.
