I'm with George Carlin at this point...if libertarians and republicans want to ignore science then we should remove all warning labels off of every product and wait a few years for Darwin to sort things out. Either you know not to drink bleach or you don't.
Except when the bird flu that's already been found in American milk mutates to affect humans and then further mutates to be infectious from human to human.
There's no way to make sure that you don't come in contact with some raw milk guzzling idiot or someone else who has been infected by one.
