Clearly then, "evolutionists should not be allowed to roam free in the land." All that remains for us to discuss is "What should be done with evolutionists?" For the purposes of this essay, I will ignore the minor issue of Western-style jurisprudence and merely mention possible solutions to the "evolutionism problem," leaving the legal details to others:
Labor camps. Their fellow believers were high on these. But, my position would be that most of them have lived their lives at, or near the public trough. So, after their own beliefs, their life should continue only as long as they can support themselves in the camps.
Require them to wear placards around their neck, or perhaps large medallions which prominently announce "Warning: Evolutionist! Mentally Incompetent - Potentially Dangerous." I consider this option too dangerous.
Since evolutionists are liars and most do not really believe evolution we could employ truth serum or water-boarding to obtain confessions of evolution rejection. But, this should, at most, result in parole, because, like Muslims, evolutionist religion permits them to lie if there is any benefit to them.
An Evolutionist Colony in Antarctica could be a promising option. Of course inspections would be required to prevent too much progress. They might invent gunpowder. A colony on Mars would prevent gunpowder from harming anyone but their own kind, in the unlikely event they turned out to be intelligent enough to invent it.
All options should include 24-hour sound system playing Richard Dawkins, Christopher Hitchens, and Sam Harris reading Darwin's Origin of Species, or the preservation of Favored Races by Means of Natural Selection. Of course some will consider this cruel & unusual, especially since they will undoubtedly have that treatment for eternity.
