Not in Claytonland, they freakin' don't. In Claytonland, rain causes iron rails to get soggy and crumble. In Claytonland, when it is cold, bullets shot from German guns freeze in mid-air and fall to the ground before reaching their targets. In Claytonland, unarmed people - beaten down by undernourishment and overwork, held captive at gunpoint - heroically resist and free every last person threatened with abuse or death, overpowering the armed guards with their bare hands. In Claytonland, it takes 100s of 1000s of these guards with guns to keep these vulnerable people captive. In Claytonland, it is simply impossible to confine some people in camps, use some people for labor, and execute other people. In Claytonland, it is also freakin' impossible to convert a regular delivery van into a vehicle in which victims can be packed and gassed to death.
Claytonland is very strange. You should visit it sometime. Going there is a very good way to escape from reality and enjoy kind of trippy fantasies and halluncinatory delusions. Really. Claytonland is quite the place.
