1) Most of the men during the Revolutionary War WERE armed with their own weapons 2) The milita really was all able-bodied men who wanted to be there, not a "National Guard", as some have suggested. 3) The patriots of Lexington demonstrated extraordinary courage to not only stand against a British army 10 times their size, but also to pursue them after the fact. 4) The 18th century equivalent of 70 "deer rifles" DID make a difference.
"After the Stamp Act was passed in 1765, Clarke objected to it, not out of concerns for the economic well-being of Lexington, but on constitutional grounds."
Not likely ! When the Stamp Act was passed, the Constitution was still 22 years in the future.
Or do the Brits have a Constitution that they've been hiding from us all these years?
