I know there is a lot frustration with Jehovahs witnesses who are more upset about a bent metal literature cart than child abuse in their own congregations. If you must have your say of disgust to them personally, so be it.
However, do not cross the line where they can file a police report and say that it was because of religious hatred. In the U.S. this can quickly involve the FBI and become a hate crime which could really ruin ones life. We are above these actions, and have rejected their nonsense justice, but we must have the faith that our governments justice will eventually prevail. We have on all our currency, "In God We Trust". Let the slow cogs of justice wear this mountain down.
As the ficticious U.S. President Andrew Shepperd said in The American President, "America isn't easy. America is advanced citizenship. You've gotta want it bad, cause it's gonna put up a fight. It's gonna say 'You want free speech? Let's see you acknowledge a man whose words make your blood boil, and who's standing center stage and advocating at the top of his lungs that which you would spend a lifetime opposing at the top of yours.' You want to claim this land as the land of the free? Then the symbol of your country cannot just be a flag. The symbol also has to be one of its citizens exercising his right to burn that flag in protest. Now show me that, defend that, celebrate that in your classrooms. Then you can stand up and sing about the land of the free."
