There is a legal recognition of what are called "fighting words." The idea is that certain words, when delivered personally, are so incendiary that any reasonable person would know the other person is likely to respond violently. I doubt this man's signs would qualify as fighting words, although if he directed some of his language directly at an individual person it might. He is staying within his 1st amendment rights, but so are the counter protestors by using the same space and expressing community disapproval of his message being delivered in that place.
