No this ain't China, but this ain't kindergarten either. Once you're no longer wet behind the ears you shouldn't expect others to hold your hand.
Ignorance of the law, including zoning regulations is no excuse. These regulations are not arbitrarily meted out to just religious folk. The next time your county draws up a general plan, maybe you'd benefit by being involved in the process or at least take the time to read it after it's been enacted.
