Yes it is reassuring to have Dr. Sowell speak out on this wisely as he always does. I also agree with your assessment of Brit Hume, I’m very disappointed with him.
A revisit to your "about" page brought a new appreciation for all the sacrifices that have been made across the centuries on behalf of America's founding ideas of Creator-endowed, therefore unalienable, individual liberty.
The final verse of your "Flanders Field" posting on the page should remind all of us of the dire seriousness of the Year 2012 election.
From the challenge of that lovely verse to the following quotation from John Quincy Adams, we are reminded of our own duty to understand the essential nature of liberty, of the "Blessings of Liberty" our Constitution was to protect, and of the fact that we are to be "watchmen on the walls" on behalf of future generations.
"Posterity!(that's us) You will never know how much it cost the present generation to preserve your freedom. I hope you will make good use of it." - John Quincy Adams
Almost certainly, we can conclude that not one of the millions who have died for our freedom risked their own lives and liberties for the sake of an overgrown, overspending coercive group of imperfect politicians in government who believe they can make better decisions for us than we can make for ourselves.
