There is a new outfit calling itself the Smokers Liberation Front which is taking a no retreat, no surrender line regarding the ‘health fascists’ (taglines are: “No More Passive Smoking. Welcome to Active Smoking!” and “Separate & Ventilate. Don’t Legislate!”).
My view is that if you are on private property (and that includes businesses), and if the owners elect to allow smoking there and you think this could damage your health, feel free NOT to go in or take a job at that place. Simple really.
