wall street vs. freedom of speech

I think wall street protesters are using the freedom of speech effectively. The amendment says that if you believe something is true, you are able to say whatever you want about the topic. The protesters are obviously against what the wall street is doing so they're protesting it. Their points will either come out positively or negatively by people all around the nation but it doesn't matter. They're just protesting what they believe, and that's totally fine. And they're getting their word out so it's effective.
