The 1st Amendment should NOT protect hate groups that endanger others.

The 1st Amendment should say 'Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances, not including those groups that endanger others.'

Groups, such as the KKK are a danger to speech and to the people 

Some terrorist organisations/hate groups believe that any criticism of their beliefs deserves death. This is a danger to society as a whole and proves that there should be exceptions to the 1st Amendment. If we are tolerant of everything, we will begin to be undermined by the intolerant, so there has to be a limit put in place.
