i know what he was trying to say. If one is for not passing laws and limiting 'freedom' for scumbags because they aren't like 'us', then not passing laws against cursing in public and freedom of speech and such can easily cause the migration to cursing at children since no laws will be there limiting that activity.
But, there are catch-all laws on the books like disorderly or harrassment or public nuissance, whatever. Whether it holds up in court or not is a different matter. There could also be protective (restraining) orders against those individuals and the judge will enforce that.
Regardless of all this, this is America. This is a land made of different people. This is land founded on liberty. With liberty comes responsibilities. It's just some are less responsible than others because everyone is different. Some like to express their differences in many ways.
It's frustrating that the age old rule of survival of the fittest no longer exists. Everyone exists no matter what now, whether they deserve to or not and pass their genes on to even more ignorant generations in the future. Gotta take the good with the bad. It sure would be nice to be able to do something about this, but, the days of the wild west is over.
