I think facial hair is dirty-looking and unsanitary.
Rationally, it's no more dirty and unsanitary than hair on top of the head. Irrationally, its what one obsessively fixates on that makes it offensive to you, like fixating on seeing women's ankles.
It's also very uncomfortable to wear.
I've never found that to be the case. Have you ever grown a beard? It's no more uncomfortable than hair on top of the head.
I think men look better clean-shaven.
That is the only rational thing stated. Personal subjective tastes. All this other stuff is not valid. It's no more dirty than hair on top of the head. It's not more unconformatalbe than hair anywhere else on the body, like the arms, legs, back, crotch, arm pits, etc.
Is there are reason you are so fixated on the chin, versus any of those other "growing zones" of the body? Bad experience with a bearded man? You tried to grow one and it came out all weird, and therefore you are not-so-secretly jealous of other men who can grown them, therefore given the power on earth you would ban all other beards so as to not have to come to terms with your personal loss of not being able to have a respectable beard? Everytime you see one, you feel shame, and then turn that into revulsion? Something like that?
I wonder if somewhere deep down at the root of this, or in this case at the follicles, you'll find something inside yourself that is being repressed by you. I say, set that inner mammal free and let it grow, let it grow, let it grow. Oh the culture outside is frightful, let it grow, let it grow, let it grow....
