Having never heard of "incels" before, I looked up the term. Interestingly, I found the definition in the Urban Dictionary. If anyone here is as "un-hip" as I and doesn't know, "incel" is slang for "involuntarily celebate". I won't post the entire Urban Dictionary definition but it's definition pretty much says the same thing as the above post telling us not to mistake lonliness for incel.
What is it about people today who seem to identify their very being with sex (or, in this case, the lack of it)? Every unmarried person should be celebate anyway until they marry. But it doesn't seem that these people are thinking along these lines. Guys who are "lonely" should put down the video games, the hair gel and manicures, get off Facebook or the other "social media", and meet people. If they have problems doing that in a world with 6 billion people in it, they need to look in the mirror and figure out what is wrong with them.
