Okay, okay.... it is weird, it is creepy, it is disturbing.
But they're not hurting anyone. There are worse... far worse creeps out there. At least these men aren't rapists, at least they don't screw corpses, at least they aren't paedophiles.
They are just sad, lonely men who haven't got the confidence to ever engage with a real woman.
Think about it - if they didn't have these Real Dolls to pour their emotion into, and to "relieve" themselves of sexual tension, then what would they become? They might become rapists or stalkers. It's very possible that Real Dolls keep these men stable.
