This is a gross misunderstanding of the concept, and it pisses me off.
Just because you have the right to free speech, doesn't give you the right to someone else's audience. It doesn't give you license to harrass. It doesn't give you license to trespass (including a properly licensed/permitted event on public property). It doesn't give you license to disruptively yell over whoever you might be protesting. It doesn't give you the right to be obnoxious for the same of getting attention, like blocking traffic.
Hijacking someone else's gathering is infringing on both their right to free speech and their right to peaceful assembly. Go have your own assembly somewhere else. There is no right to disrupt. If you can say the same message anywhere else in the country without restriction or repercussion, then you're freedom of speech hasn't been infringed.
That said, and even by that standard, the US is the most tolerant of free speech by far.
