Right on. I'm not going to bother reading the comments, as I'm sure that the free trade mongrels have been dropping their talking points all over you. But you're absolutely right, keep up the good work.
When hoping to educate people who have long been told something different, you have to be able to stand up to that and continue to try and dialog with those who will carry on a reasoned discussion, and ignore the pure detractors.
At least, that is what I try to do.
