Too often the reasons we end up legislating every little trifle is that with out constraint, we will do the most incredibly ignorant of things under the banner of freedom. And most always those freedoms affect others and remove their freedom.
The freedom to smoke in a public place removes from me my freedom not to smoke. The freedom to drive 130 miles per hour often results in negative affect on the lives of others.
The freedom to express hatred for war has it's place, as does the freedom to smoke and run 130 miles per hour. There are acceptable places and times for expression of freedom. Freedom is not the reckless expression of right, but the thoughtful execution of that right in the appropriate place and time with thoughtful consideration of those whom it may affect.
It is clear that some in society often lack judgment in execution of those rights, and steal the freedom they profess to express (and protect) from those whom they, without thought, push their freedoms upon. Just because I can do something, does not mean that I must do it. And there are those who simply "do", because they can, without regard to the consequences and the affect it has upon those around them.
Freedom is also, choosing to do what is right, and in the right way and with respect to those around us. It is a sad thing that we have to in-act ordinances and laws to curtail the infringements of acts of freedom by those who are only focused upon themselves and their cause and not those around them.
Though most would agree the current topic centers upon what most consider the obvious infraction of common decency, we as human beings seem to have the need to be restrained by law or we will push the boundaries of acceptable limits on any and every issue and use the excuse it is our right to expression, even if it usurps the rights of those around them.
