Of course I'm fine charging people who throw lit cigarettes out the window. That's a consequence of your own action. Taxing everyone who smokes, even those who don't litter, is like blaming all gun owners for a mass shooting. Or taxing every fast food bag because you see those along the highway, even though the vast majority of customers throw them in the garbage. Assuming the worst out of any group, and preemptively fining/regulating them is not a free society. You give people freedom, and when they fuck up, they answer for it in the justice system.
Personally, I don't care if you gut your larynx with tobacco. I just hate that smokers are piggies. Inconsiderate piggies.
