It wasn't long after moving to the US before I found myself in a heated discussion about math teaching.
Not the perverse pride of "Oh, I was always hopeless at math", but a serious discussion about the best teaching methods in K-12.
As the conversation went on, though, I became more and more puzzled by the intensity that my partner brought to the discussion. It seemed that he was less interested in talking about the different ways in which people learn, and what might be best in a mixed classroom; more alarmed that the correct, "traditional" way of teaching was being undermined by dangerous innovations promoted by impractical university professors.
Fast forward to today's polemics against "Common Core math" (see the meme above, and many like it which you can probably find in your Facebook feed).
