You can't get a little pregnant, neither can you almost fly
an airplane.

Taxiing is not "almost flying" an airplane. It is "not flying" an airplane.

A non-yet soled student can have an accident
at 10 mph, even death is not unheard of at low speeds.

A 20,000 ATP CFI can have an accident at low speeds, and if he kills
himself he's just as dead. Ratings are not a shield. Your statement is
irrelevant.

That is my opinion and your are entitled to
your opinion if you are a certified flight instructor.

I am entitled to my opinion even if all I do is draw pictures of
airplanes and make engine noises in my cubicle.
