What about a political movement mixed with god-talk that advocates the violent end to the Constitution?
To root out Wahabism in America may require resort to extrajudicial means, unless we want to infiltrate every mosque and charge each seditious imam one at a time.
Any measures the government takes against the Wahabis collectively just because they adhere to the Wahabi sect of Islam create legal precedents that may in the future work to the disadvantage of other, non-Islamic sects.
