If you are going to cut and paste portions of that argument that attempt to support your argument, you had better read the entire text.
The right to assemble allows people to gather for peaceful and lawful purposes. Implicit within this right is the right to association and belief. The Supreme Court has expressly recognized that a right to freedom of association and belief is implicit in the First, Fifth, and Fourteenth Amendments. This implicit right is limited to the right to associate for First Amendment purposes. It does not include a right of social association. The government may prohibit people from knowingly associating in groups that engage and promote illegal activities. The right to associate also prohibits the government from requiring a group to register or disclose its members or from denying government benefits on the based on an individuals current or past membership in a particular group. There are exceptions to this rule where the Court finds that governmental interests in disclosure/registration outweigh interference with first amendment rights.
Since there is not any evidence that the nazi group who cancelled their march were involved in any proven illegal activities, they were granted their marching permit.........
So back to the original question, who determines what is permissible, the U.S. Constitution as interpreted by YOU?

Thank You!
