This is an interesting debate and a good one :). I can't say that I agree with the posters whose responses are in the vain of, "If its legal I'll use and the rest of the world can kiss off. Stand together or fall!" We've got to keep in mind that laws are only the minimum standard of behavior in a civil society, essentially intended to protect us from anarchy.
In my town there is no law that says I can't paint the outside of my house entirely black with giant white skulls and crossbones all over it. I may not be breaking the law, but am I being a good neighbour or a conscientious member of society? Am I really doing myself or anybody else any favours by excercising my rights in this way?
