I'm always impressed by how much research you put into your articles, although it often seems the simple logic ought to be enough. Here, the facts clearly do matter, and the issue is alarming.
To me, incels are one facet or symptom of the larger problem of male children failing to reach cognitive or social maturity. (I wrote a half-satirical take on that recently, based on the premise that men have given up on education and will soon be good for little save as drones.) Another facet is the prevalence of misogynistic players who seem to dominate the dating sites, seeking not relationships but hookups.
