They MAY lead to breaches of peace. If the peace is breached, punish those who are breaching the peace.
Are you saying that we may prohibit offensive behavior which harms no others through force, fraud, or theft, simply because that behavior may result in a breach of the peace by others?
Sigh - Again paulsen; --- Public displays of offensive behaviors are harmful as they lead to breaches of peace. Are you really this obsessed? Can't you 'remember' that you agreed with this answer at #98?
They MAY lead to breaches of peace.
At #98 you said "true", -- as they do indeed lead to breaches. Now you quibble, typically.
If the peace is breached, punish those who are breaching the peace.
The peace is breached, and those who initiate breaching the peace [in this case the masturbator] are restrained by removing them from the public eye.
Are you saying that we may prohibit offensive behavior
We can reasonably regulate public aspects of such behavior, yes.
which harms no others through force, fraud, or theft,
Public displays of offensive behavior are a use of force on unwilling viewers.
simply because that behavior may result in a breach of the peace by others?
Offensive behaviors ~will~ result in further breaches of the peace.
Libertarians and other rational people know this to be true. -- Democratic quibblers equivocate and troll the issue.
