Good, go stink up someone else’s breathing space. Smokers think it’s freedom to smoke where and how you want, at the expense of the ‘freedom’ of a non-smoker to breath clean air and not stink. Ya’ll smokers stink!
Actually, this is a property rights issue.
If you don't want smoke in your home, that's perfectly fine and within your property rights.
If the airline or restaurant permit smoking, it is their right as the property owner and that air is a free good in their space, just as is the lighting/darkness/absence of sunlight (another free good).
If you, as a "renter" of the airline or restaurant's property rights, thinks smoking is bad, your choice is to leave or not...unless you abhor property rights like the left statists and believe EVERYBODY gets to have a say in whether or not people can smoke, drink, must brush their teeth before entering, wear deodorant, play loud rap, or set a dress code on SOMEONE ELSE'S private property.
Furthermore, if you give license to the state to ban smoking in airplanes and restaurants, then it is a hop, skip, and a jump before that state tells bakers what kind of cakes they can make.
I don't smoke, and I'm willing to "endure" the "little offenses" that accommodate the joys of private property that typically set off snowflakes. As they say, if you don't like the weather, then move.
I just hope you realize that the template for getting rid of smokers (“otherizing,” incrementally outlawing, excessively taxing, etc), is now being used in an identical way against gun owners. And very sympathetic people with sad stories about how guns hurt their loved ones will be a part of it all.
