My tl is full of wtf re some "incel" garbage that's been going around, and I REALLY wish it wasn't. Even engaging with some ideas spreads their poison. Just shove it back into the creepy hole it crawled out of, remind yourself women are human, sprinkle salt, & go.
Incels are also female. They are people who have been spurned by the opposite sex through lack of success, money, looks, charm, etc. Also I remember incel forums on the internet 15 years ago. It's far from a new thing.
