the second amendment
-the first sentence of the second amendment is called a PREAMBLE.
-The reserve militia or unorganized militia, created by the Militia Act of 1903 which presently consist of every able-bodied man of at least 17 and under 45 years of age who are not members of the National Guard or Naval Militia.
-the bill of rights was written to protect preexisting rights that are inalienable
-a "well-regulated militia" is one that is well functioning and disciplined
-in the rest of the bill of rights if a right is an individual one it is directed at "the people" if it is for the states it will mention "the states"
that ought to cover a fairly wide scope and provide a good base. Glenn Beck's book "arguing with idiots" has a whole chapter devoted to counter points made by the anti-gun side. and if after all that someone can come up with a point that stumps you, I got free time and nothing better to do than shoot holes in it. I'm sitting at my keyboard anyway.
