Gotcha, thanks for the explanation. I think what you are saying is that Twitter is not violating US law for restricting free speech, but they are violating a natural law of God. That law of God is somewhat specific and allows for content moderation on websites that are more like clubs, but does not allow of content moderation on large, general-purpose websites.
In summary yeah. There is often confusion when discussing law around whether one is arguing what the law currently says as opposed to what it ought to be changed to say. I am talking of the latter. But when we talk of an “ought” in that sense we have to appeal to a system of morality that we think the law should conform to. I think I am using the same system that our founders did. What John Locke called Natural Law.
