You seem to have missed post #18.
But for your analogies, in general, for other areas, Here's the problem I see:
We can all grant that public nudity is offensive. Right ? And we can all agree that grave-robbing is offensive, right ? And we can all agree that "bringing in an excavator" would be offensive, right ?
So in EACH AND EVERY CASE of what you use for examples, they are an example of obvious offensiveness. Right ? Not only could you offend people if you did them at a church, but you would ALSO offend people for doing them in a park, or school yard or beach, etc... Right ?
But is the act of md'ing (while clothed) inherently "offensive" ? Why this notion ? Everyone hates md'ing and finds it offensive ? If anything, I find it to be quite the opposite: Strangers come up and ask what's the best thing you ever found. Or "where can I buy one of those ?", etc...
But this is all a moot point. Because I can agree that my initial inference that some forms of private property have a public feel to them, yet , as said in #18, I recant of that notion. So it's a moot point.
