We have laws against conspiracy..
You cannot use either a church or a mosque for such things. Further, you may be RICO'ed and have the whole place knocked down like bowling pins. This is as it should be.
This has no bearing on the thousands of peaceful muslims someone (who shall remain nameless, but began this thread) wishes to persecute because of their religion.
It's unjust.. You shouldn't do it to a peaceful: Christian, Jew or Muslim.
It's not scriptural and it's certainly not Constitutional.
Suppose the church or mosque being used to exhort young Muslim men to suicide attacks is located in a foreign country away from the reach of U.S. laws, while the young men filled with hate, board American airliners and kill 3000 Americans? What should we do?
