I was thinking the same thing.
To all those outraged by this missionary law, how would you react if hundreds of foreign Hindu missionaries descended on Appalachia and began converting poor and uneducated people away from Christianity by the thousands, often with financial inducements? I may be wrong, but I very much doubt you would be joyously proclaiming the virtues of free speech.
How is that different from the moonies or harry christners? Nobody is screaming to put them in jail. And good luck going to the Appalchia. They don't look to kindly on trespassers.
