I'm not disputing the facts that melanin will not fully protect you; I was disputing the claim of it damaging the melanin. I cannot find anything that corroborates that statement. If you know of any, please post a link. I don't mind being proven wrong if there are facts.
Actually, part of my explanation wasn't fully correct:
Independence Was Not Declared on July Fourth: The second Continental Congress actually voted for independence on July 2. In fact, John Adams wrote to his wife, Abigail, predicting that future generations would celebrate July 2 as Independence Day, saying, "The second day of July, 1776, will be celebrated by succeeding generations as the great anniversary festival. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illumination, from one end of this continent to the other, from this time forward forevermore." July 4, 1776 is significant because that is the day that Congress officially adopted the Declaration of Independence document, but contrary to what many people believe it was not signed on the July 4. The official signing ceremony occurred on August 2, which is when most of the signers affixed their names to the document, but other representatives signed the document throughout the summer of 1776. Finally, there is no historical record of John Hancock saying that his signature is that big so that King George could read it. It has been suggested that Hancock's is by far the largest signature simply because he was the president of Congress.
Art, of any form, develops the mind. It exercises a part of the mind that is not always used. So yes, it should be taught because the idea is to enlighten and expand the minds of our youth. I had art class in one year of junior high and I was horrible in it. But i still think it's worthwhile. The only thing artistic about me now is that I taught myself to play the Native American flute.
The fourth is the celebration of the signing of the Declaration of Independence. But all the rest that you listed are true. As far as the death of British soldiers, there were many casualties on both sides. But the fight for freedom was worth it to get out from under England's rule and taxes.
