At Least I can Still Smoke in My Car!

I just saw that on the bumper of a rusted out blazer. I thought it was odd for a number of reasons:
1) If you have nothing of relevance to add, by all means stick it on your vehicle
2) Is the fact that you like to smoke supposed to endear you to other drivers?
3) Is the fact that you can't smoke in my face supposed to outrage me (get me on your side?)
4) Are you complaining of loss of rights? Because for years you've had the right to cause cancer in people you don't even know... What about our rights?

I just thought that it was the strangest thing. I think it's nutty how smokers want to try to refute the 'smoking is bad for you and those around you' type of logic. Not everything people like to do should be allowed in all public places, things like:
Having sex, masturbating, doing drugs, picking their noses, listening to explicit songs, looking at porn...
I could think of many others. Sure everyone should have the right to do what they want when in private (well the drugs are still illegal, but you know what I mean). But any of those behaviors at a restaurant or a bar will get you into trouble, tossed out if not arrested. There is a time and place for anything, especially if it can hurt others around you.
Tell me where I'm wrong.
