What crosses the line of "free speech" for you?

Example: There is a planned parenthood down the street from my house. every Tuesday some people get together and protest. Most of the time I just hang my finger out of the window and them and sigh but this past Tuesday they had huge billboards of aborted fetus’ and one sign that said OBAMA-NATION. I think this is going to far. I had to stop the car and get out. I love the fact that we live somewhere where we can say what we want but I do not believe that you can have free speech without some sort of consequence.
