Celibacy is a lifestyle choice. Wanting sex and not having it, is not what I would call “involuntarily adopting a lifestyle choice”. Incel is rather, like you said, the feeling of being “unfuckable”. The problem, as I see it, is that the majority of men in this position are voluntarily “unfuckable”. They are actively being unlikeable by doing things like treating women like they they should be required to like them, which in turn, makes them “unfuckable”.
Doesn’t change the number of senators, sadly.
