This is a tiresome argument. The first amendment guarantees freedom of the press (ie, the printing press). The clear aim is to guarantee not just the right to speech, but also the right to _distribute_ that speech. In fact, without that the right to freedom of speech is of limited value. This doesn't mean Facebook couldn't ban political ads, but it does mean it would be unreasonable for the government to do so.
And yet we regulate swear words and nude imagery on broadcast television because the airwaves are a limited public resource. First ammendment absolutism in the face of rapidly changing technology is way more tiresome.
Maybe the reasonable answer is that you shouldn't, especially in the face of rapidly changing technology, which nowadays gives us huge choice of what to look at. The example of outdated censorship doesn't make a valid argument for more restrictions.
