I voted "yes" because I think it's better they be allowed to state their opinions freely, thus showing the world what they are, than that they be couted martyrs for the cause in being shut down.
Nevertheless, I don't think the Freedom of Speech should trump all other laws and regulations at any time. So for instance, if they're disturbing the peace (say, at cemetaries) they should be removed. And if they abuse their children (I think what they force their poor kids to do and say constitute abuse) the kids should be removed. Etc.
