Folk models can be very resistant to change, because they feel "natural" to the people who hold them. When you challenge them, you challenge the natural order people have constructed for themselves. And every generation of students brings these folk models to school with them.
A few linguistic and anthropological things that make me cranky every semester:
- "Languages" are better than "dialects"
- a "double negative" really means a "positive"
- words like the and a are "adjectives"
- believing that ancestors can talk to you in dreams is "superstition," but believing that a wafer turns into the body of a man who may or may not have lived 2,000 years ago is "religion"
In some of the following posts, I'll deal more in depth with these and other sources of my crankiness.
