Not putting any words into anyone's mouth:

  By “free speech”, I simply mean that which matches the law. 

  I am against censorship that goes far beyond the law. 

  If people want less free speech, they will ask government to pass laws to that effect.

  Therefore, going beyond the law is contrary to the will of the people.[1]

So there doesn't seem to be any kind of carve out there.
