Thanks for clarifying. It's still not clear to me that a website is a common carrier. Do you have a reference I can look at regarding the "no moral expectation…" argument?
Re 'no moral expectation of speech for private businesses', a frequent argument made against free speech is that free speech is only required to be enforced by the government, the first amendment doesn't apply to private companies. This is true, but assumes there is no moral imperative to compel private companies to enforce free speech.
