Gabz, following that line of reasoning, public nudity laws are tantamount to precluding peacable assemblage in that those who may choose to go naked have to seperate themselves from the assembly.
No, it isn't, because we are not talking about being in public, but rather patronizing private establishments.
There are laws permitting nudity in certain private establishments and forbidding them in other places...provided certain regulations are met.
Smoking bans in private business establishments, that have met all laws and regulations prior to such bans is different.
