"A private business that opens its doors to the public is bound by the laws that are deemed reasonable by the representatives of the people for the public use of that business."
You just made it clear that you do not believe in private property. You prefer to give the ability to the "majority" to confiscate private property as they see fit. With this statement, you must also support the ED cases that are stealing property from one private entity to give to another private entity in the interest of "public good". Would you stand by and allow these elected representatives to confiscate a church to allow a private contractor to build condos?
"For example, consider fire safety laws, occupancy limits, sale/use of illicit substances, etc. Prohibiting smoking is no different than any of those other restrictions on a "private" business."
No difference? You can't tell when smoking is allowed in the business? Or is it that you can easily tell the set up of the fire protection system?
"As to my "selfish views," it is those who wish to smoke that are exhibiting selfishness. As I observed before, everyone has to breathe, but no one has to smoke."
It is not your rights to not smell cig smoke, nor my right to smoke, it is the property owner's rights that are being stolen for your convenience. No more selfish act could be envisioned. You need to read WW's article, titled "Harm is more than a two way street". A quick search will get you there.
