CMV: History teachers should be forced to say "This is the most widely accepted view at this time, however, there is still debate among some historians" at the end of every lesson

Or something of the like. I recently graduated college, however, when I was in middle school and high school, my perception of history was that all of it was just facts that everyone agreed on. When I got to college, I found out there was a lot of debate among historians on the issues we were learning about. This initial misconception really frustrated me, as I felt it would have been much easier to understand if I had been presented with multiple viewpoints as a young age.
