G.E., come back after you find a ninth-grader to explain to you the difference between a function and its first derivative. Or a second-grader who can explain to you the difference between the beginning of a path and its end. Or a kindergartener who can explain to you the difference between forward and backward.
Mike, I happen to be someone banned from the Outright forum for making fact-based characterizations of the statements of Outright leaders, so thanks for exhibiting your ignorance.
