Really, you are concerned about anyone who would "be screaming" about quoting the Declaration of Independence? Do people really quiver uncontrollably at the thought of someone - anyone - being offended?
Should we now avoid teaching our children about the Declaration of Independence? Should we no longer recite the Pledge of Allegiance? Where do you propose it stop? And what if these omissions offend me? Is it okay to offend only certain people without concern? Is that now legitimate?
The truth is that our right originate from our Creator. They are not man-made. They are not devised by a government. They are derived from our Creator, just as the DOI points out. If that offends some, then perhaps they need offending to wake them back to reality.
They are using the Declaration as decoration, is what I mean to say. Kind of a verbal red white and blue bunting. They don’t want heavy philosophical issues. They are lost same as all other unbelievers, and believers railing at them about that are missing the gospel point entirely.
