It is ILLEGAL to engage in disorderly conduct.
If all the do-gooders here would accept the argument that people should be held accountable for their actions that cause harm to others BUT NOT be held as criminals for doing something that is of their own concern then I think we could find a happy medium.
But it sounds like people have a list of what they are comfortable with and not comfortable with and want to legislate based on that.
Well I have some type of movies I like and some I am not so comfortable with (really gorey movies are not my thing).
But guess what? It isn't my perview to tell the rest of you what kind of movies you should find entertainment in. Nor is it within my perview to tell you what chemical substance you should put into your body.
Folks that use illegal substances aren't asking anyone's permission from the get-go. This fact will never change: there will always be people who seek drugs and there will always be suppliers to meet the need (or create it?).
Movies, when watched, do not enter the blood stream and markedly change the affect of the viewer. Cocaine, smoked, does so rapidly and dramatically.
Personally I believe we can be affected negatively by many different things, some legal/some illegal. For the greater good of society, and as a result of observation over time, some things are given a greater prohibition.
Valium was dispensed like candy in the sixties, until it's addictive potential was made manifest. Plain Jane housewives, not drug-addled bums, showed how certain substances are inherently problematic.
