Then I expect similar penalties for alcoholism, homosexual behavior, (currently) illegal drug use and the like. All those who engage in that behavior are significantly more at risk for health complications due to that behavior, just as smokers and fatties are.
Or heterosexual behavior outside the bounds of marriage. All those who engage in that behavior are significantly more at risk for health complications due to that behavior. Why should I have to pay for someone who gets gonorrhea for some casual bar hookup?
