Do you DENY that Reagan said libertarianism was at the heart of conservatism? If you don't "deny what is," then, PLEASE spare a few words here to square Ronald Reagan's stupidity with your wisdom.
Do you DENY that Thomas Sowell is one of the finest conservative minds in American politics today? If you don't "deny what is," then PLEASE show me WHERE Thomas Sowell falls into the leftist camp. Show me his words (they are plentiful).
"Silly" is a very stupid word for you to be tossing around.
Ronald Reagan was no libertarian.
That is why you pluck that quote out of a 1975 interview that candidate Reagan had with a libertarian publication, first he said something that made Reagan such a smooth and effective politician, he warmed up his libertarian audience with a sympathetic bone, and then he proceeded to tell the libertarians how he was a social conservative and not a libertarian.
