Second hand smoke is a huge "hot button" in America today. I understand and even support a lot (not all) of the no smoking laws that are in place in some states. I am grateful that cigar lounges still can get a pass on those laws and I think there is good reason for separate laws for cigars.
I do not smoke cigars around children as I do not want to expose them to my second hand smoke. I cannot blame a parent for not wanting someone smoking around their children. Since most public parks are designed for "family" use I understand the desire to have them be smoke free.
I also see a lot of cigarette butts laying around in the public parks in my area and I find that infuriating as I find any litter infuriating. Seeing those butts gives the general public one more reason to dislike smoking. (That being said you don't see Mt. Dew being regulated because people leave their empty 20oz bottles laying around the public park.)
I think its unfortunate that people cannot be considerate of others so the government feels the need to step in and regulate it but I do understand the "why" behind such regulations. Unfortunately a few inconsiderate smokers can make all BOTL and SOTL look bad to the general public. Also, the general public does not see any difference between cigarette smoking and cigar smoking so you have to keep in mind that the actions of ALL smokers play a role in these things.
All of that being said I live in rural MN and have 160 acres of my own personal "park" that I can use. If I lived in a larger community and lived in an apartment that didn't allow smoking on the property, and a park was my only outdoor option I am sure I would be less "understanding" of such regulations.
