OK, so yes, your not in immidiate danger, and maybe somedya there will be a cure for lung cancer. Actually there are all sorts of cures for cancer. The english are just tired of paying for them so they are making it as hard as possible to smoke. As you have all figured out, the danger is exagerated, and the public health argument is a screen to opress people and control their behavior.
And no, I don't kick your ass for breathing near me, I sue you for causing hurricanes with your emission of global warming gasses.
