Seatbelts save lives, eating broccoli instead of big mack’s saves lives, exercising an hour a day saves lives, not smoking saves lives, etc etc etc...... do you want the government mandating all that? If not, why not? If you do, then someone lied to you when they told you you were a conservative.
Fear not; I was a conservative from the day I first read Solzhenitsyn's The Gulag Archipelago and that was back in the early '70s. Nothing infuriates me more than the idea of some do-gooder with a government gun pointed at my head trying to tell me what I have to put into my body "for my own good."
