While White should not be censored, we have a right to object to his view. The Legislature can do even more. It has the ability to enact laws that impact directly on speech. For instance, when the Legislature passed the mandatory abortion counseling bill last session or the so-called cocaine mom bill this session, the Legislature interfered in the speech that goes on between patients and doctors. But for the pro-life majority in the Legislature, obviously their extremist supporters have to be satisfied.
Abortion protest is the area where the distinction between speech and conduct is most visible.
Anti-choice demonstrators don't only engage in protected activities such as marching or praying outside clinics, they also physically obstruct clinic entrances and engage in physical violence against health care providers. The trouble is there is no bright line between speech and conduct. The Brandenburg test of a clear and present danger of imminent lawless action is the closest we get. But on the other hand, it is not always so difficult to separate conduct from speech. In the early 90s when there was violence at the boat landings in northern Wisconsin during spearfishing season, the ACLU of Wisconsin went to federal court to get an injunction against violent conduct such as throwing stones at the Chippewa spearfishers, or firing off rifles in the woods nearby, or using powerboats to stir up a wake around the fishing boats.
