(5)are all Univ.Western Ontario mathematicians like Ajneet Dhillon, Matthias Franz, John Jardine as dumb as Dan Christensen, teaching a Conic section is ellipse, when in t ruth it is an oval?

Now the reason Franz makes so many geometry mistakes, like Dan Christensen is because both were mistaught, very much mistaught as seen in the below exchange -- what is distinct and not distinct and so they cannot tell the difference between a circle, ellipse or oval. Can they tell the difference between a plant and animal or did they miss that in graduate school.

Franz, do you understand that
Ajneet Dhillon is distinct from Matthias Franz which is distinct from University of Western Ontario.
Me thinks:: Me thinks Franz has much to -- de-learn as he grows older -- in order to become wiser
Franz, do you see that a oval is distinct from a ellipse
