Oh, please.  Who or what is “eroding” your freedom to smoke in a restaurant or bar  in Mississippi?  As I understand it, the state-wide ban only applies to government buildings, and it’s a local option to enact any other smoking ban. 
 
(If I am incorrect about that, I apologize.)
 
But, assuming that is correct, if someone is eroding your freedom in Mississippi, it is presumably your LOCAL elected representatives.  If you don’t agree, vote ’em out.  That’s the American way.

I agree it is wise to be diligent about watching over those who serve in government office.  And I also agree that if government officials were really serious about banning smoking, they’d ban the sale of cigarettes. Controlling the use of a “legal” product bothers me, as a lawyer.
 
But they won’t ban the sale of cigarettes, because they don’t want to deal with a black market and they don’t want to give up the tobacco tax revenues. 
 
Having said that, the rhetoric about smoking bans signaling the end of democracy drives me crazy.  There are a lot more serious assaults on our freedom to worry about than a smoking ban.

And, for the record, I’m one who likes the smoking bans very much (as you might expect).  I especially like them in the United Kingdom, where I can now go into pubs, which I thoroughly enjoy, and which I couldn’t do previously because of my sensitivity to smoke.
