Who says July 4th is Independence Day?
It's based on the date the Congress met to approve/disapprove the Declaration.
It's written on the top of said Declaration... hence the holiday. Overtaxing yourself with an attempt to make it some other date is just sour grapes. You didn't really want those dirty colonies anyway... didn't fight too hard... M'eh, let those backwards colonists see how they'll do without you, eh?
Thanks for thinking that I care one way or the other, I just saw the news item and posted it.
