Then prove it. Surely you accept that everyone on this list understands to some degree and acknowledges abstract analytical (non visual) thinking. I think the task is up to you to prove that this mysterious non abstract visual thinking exists and is up to the task of mathematics. I have found no evidence of it. Sure, there are plenty of classrooms where teachers stand in front of students and display a visual, ask the students if they "see" and the students nod their heads. But they aren't seeing math. Visualization is a lot of things to mathematics but the source of generalized abstraction in thought it is not.
