I think you are right. I think the reason I didn't really know anything about ID was because it's essentially a non-issue in Canada. I've never seen it mentioned on the news and I don't know anyone who believes it (at least no one who has admitted they do) though maybe I'm sheltered.
I don't think it's that you're sheltered. It's the same here in Sweden. If it wasn't for the Internet, and me being interested in skepticism and woo-beliefs, I would probably never have heard of it either.
