This is about the most clear you have been in any post I've seen. But it seems quite conflicting.
You've correctly identified a conflict, but not its source: in a nutshell, the source is Mojave's attempt at sophistry. Reagan can be called a protectionist because he raised tariffs on products from Japan, but Reagan cannot (according to Mojave) be called a free-trader because he lowered tariffs on products from Canada. There's your conflict . . . .
In your opinion, can one be a free-trader and protectionist at the same time?
I didn't call Ronald Reagan a protectionist. That was you.
