Yeah, that’s the common interpretation.

If we need an amendment to extend that to all entities and forums, public and private, then I’m all for it.

I'm not sure a Supreme Court ruling that I'm prohibited from deleting blog comments actually represents an extension of my freedoms...

> that's the common interpretation

Hardly an interpretation, it's stated in black and white :

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."

Just because the amendment explicitly addresses the government, doesn’t mean that non-governmental entities shouldn’t respect the vision of the amendment. Not everything in this world needs to be driven by legal compulsion.

What we really need is an honor code, or something even simpler: mutual respect for other people’s thoughts and opinions.

The vision of the amendment is the government getting out of the way so that progress can be made by the vigorous use of choice of what ideas to publish and distribute by private entities. Private entities promoting the ideas they like and not doing so with those they dislike with all their resource are the purest embodiment of that vision.
