You are right, it doesn't say that. It does imply it, at least in my opinion. See, free expression should be a social ideal. Free speech should be something we strive to allow, even to facilitate.

And yes, yes that includes speech from hateful Nazis.

Please keep in mind that Nazis would absolutely harm me, if given the chance to do so. I'm quite distinctly not white.

But, the goal should be allowing even the deplorable to make use of their basic human rights. The Constitution says what the government cannot do. It should also serve as a baseline as to how we should model our society.

We should facilitate free speech, freedom of and from religion, security of our papers, innocence as the assumption, etc... Well, we should if we care about fostering a society where people can enjoy their liberties. Rights shouldn't just be allowed for those we approve of. If they are not allowed for everyone, they are privileges and not rights.
