Phys-L among other sources have taught me not to ban centrifugal
forces; they do belong to more advanced courses and modern
physics.
The question is whether such a hard stance in intro courses causes
hardship in the advanced courses.
I agree that using the term "centrifugal force" (like "centripetal
force", by the way) confuses students. For this reason, I prefer
using the phrase "apparent force away from the center" instead of
"centrifugal" until the students get used to the idea.
