It is my understanding that, currently, the following speech is of "type B, disallowed" in the US:
* Shouting fire in a crowded theatre
* False advertisement
* Medical or legal advice (allowed, heavily regulated by the Government)
* Advocacy of force or criminal activity
And I assume, many others that I do not know of.
Unless you are arguing that there is no such thing as free speech in the US, then it must be that you can have "free speech" while still having some limitations.
There is a cardinal difference in the US between speech related to public interest, such as anything that has to do with politics, religion, military actions, and speech that's only about private matters, such as whether or not your neighbor has a perverted sexuality. The second category is not nearly as protected as people usually think it is.
