I'm sorry you feel like you have to assume the worst about your interlocutors. I wasn't lying, I was inadvertently mistaken. I explained & apologized for the mixup.
If you actually believed your bullshit about the first amendment, then you'd also think you have no right not to be murdered--because hey, it doesn't say nobody else gets to kill you, right?
Well, murderers are not tried for violating the constitution. They're tried for breaking homicide statutes. The analog to broad free speech claims based on the 1st amendment would be if someone claimed that murder violates your 8th amendment rights.
I don't think the first amendment is the only thing that matters in free speech, nor did I ever say that. I do _know_ that the only thing the first amendment (which was the only thing I responded to if you care to re-read my @37) protects against, though, is government interference. That was the entirety of my first comment here.
I don't know why you think you know what I think about corporations and free speech. FWIW, I think the role to which critical information infrastructure is privatized is a bad thing. I'd love to have significant publicly owned media (though we both know that's never going to happen in the US). But I do think that there is a strong case for media and social media to contain some degree of moderation. Looking at YouTube comments, say, gives us a pretty good sense that entirely unconstrained speech doesn't promote diversity of viewpoints, but crowds out a significant share of viewpoints. Frequently those least represented in the public sphere anyway.
And I do think that different media platforms aren't just allowed to, but should think about what type of community they want to build and what that means for the type of speech they want to moderate or not. If there is, on one side of the spectrum, something like 4Chan, or even Reddit, with hardly any limits on speech, why shouldn't there also be fora where people can go and expect _not_ to be exposed to certain forms of hate speech. (And, you know, if some crazy Christians want a social network where everyone who says something "blasphemous" gets banned, I'm good with that, too).
