This one Psalm is acknowledging the Lord as the creator. Gee, that reminds me of another acknowledgement -- THE DECLARATION OF INDEPENDANCE!
If they're going to get serious about obliterating all mention of God, then we'll need to redact the Declaration of Independance, a foundation of our country, 1776:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights..."
IMO this proves that they're WRONG, because unless they want a revolution, they can't touch the Declaration of Independance.
