I am also curious about the charge that Ron Paul is an isolationist. Isolationists usually favor protectionist measures, in addition to non-intervention; Ron Paul, on the other hand, has a rather extensive record of supporting free trade, as well as "peace, commerce, and honest friendship" to foreign States that will reciprocate. In other words, he doesn't sound like an isolationist to me, unless you're using a different definition that nobody but you knows about.

I absolutely agree. Ron Paul is no isolationist; he is quite the opposite. Isolationism is, by definition, a policy of nonparticipation in international relations, be they economic, military, political or otherwise. Ron Paul is clearly not of such a mind, and the continued suggestion that he is demonstrates that those who hate him are severely lacking in either honesty or intelligence. Of course, it is possible that both are wanting.
