First of all, I didn't ask for the government to pay for my healthcare. I pay my own way, as do the majority of responsible adults in this country. This collectivist bullshit was shoved down my throat, against my wishes. Part of the reason why I oppose it has been brought to light by your comment. I don't want your moralizing about why you think I'm a defective human being and should pay accordingly.
So please, spare me your righteousness. There are many things that people choose to do which can possibly degrade their health or put them at risk of bodily harm. I'm sure if I scrutinized your lifestyle I could find at least a few that I could tut-tut. You're just falling in line with the latest trendy socialist busybody know-it-all jihad. Since the battle to demonize smokers is pretty much won, it's on to the next target.
You aren't "defective" because you're overweight anymore than I am "good" because I have money or "bad" because I come from the South / Midwest. Our life is the sum culmination of all the choices we have made up until this point in time. Some of them are good, some of them are bad.
As long as we own those choices, everything is okay. The problem comes when people start demanding their friends, family, neighbors, and fellow citizens pick up the tab. Morality has nothing to do with it, it is about justice and fairness. A man should be able to determine his own future and destiny, not have society impose it upon him. If I start smoking tomorrow, you shouldn't have to worry about your taxes increasing because of my bad choices. The current system forces that to happen and it is wrong.
