The political problem with letting the "Inferior " cull themselve is that
A) they try to take US with them
B) Our leaders wouldn't have anyone left that was dumb enough to believe everything that they said-so no Re-elections
Yes Idiots do bring these things down on the rest of us. Two kids a class behind me in school decided to build the ultimate firecracker. Big enough to knock down a tree no less
It went off while they were finishing up putting in the fuse.
IIRC they had 10 fingers, 2 eyes and one functioning ear between them when the dust settled. The tree was still standing
Today we would call their Firecracker a Pipe Bomb but what the hell, it was just a couple of kids having fun
PS. I believe that they were both allowed to Reproduce
