Well I think you all can agree, that some people are just TOO ugly to get close to.
You're walking down the street and you see a man with long, greasy haired, one eye, sallow, yellow eye and face, rotting teeth, bloody cracked lips, hairy ears and nose, unibrow, massively overweight, sweat stained clothes, and etc.
There's not anyone in their right mind that's going to willingly walk up and start a conversation or god forbid have sex with.
There comes a point where you just have bad facial features, and then there's bad hygiene...I think the latter could be rounded up and "disposed" with, no one likes the smelly kid.
