Universal health care from the Stupid party might seem better than the same from the Evil party but they will end up being the same.
I understand your cynicism, but I do believe that environmental laws written by Republicans are far more respective of Homo sapiens than are laws written by Rats, and we've seen that difference in numerous states.
Besides, what is the solution to the problem of being able to ultimately identify the likelyhood of each individual's propensity for disease? Would you instead rely on laws prohibiting discrimination in insurance and employment based on genetics? Even if you did, individuals with "clean" genes would always be able to get better rates, simply by voluntarily offering their DNA for a test. Once you have that going, then anyone who won't offer theirs is automatically suspect, and rated accordingly.
