Discrimination: Why do smokers allow it to continue?

The "land of the free" - that is what the national anthem says. It is an oft-repeated saying but, in many circumstances, it is simply untrue. People of all of racial minorities complain vociferously that, despite the claims of equal justice for all, they still have an uphill struggle to face if they ever want to see their children with this level of rights. Yet there is a discrimination in this country that affects all races and ethnic minorities. It is not a crime and yet participants suffer a very systematic form of discrimination. These people are smokers. But please put aside your prejudices against smoking. This is not about smoking, this is about discrimination.
