Hold on a second! The student accused the professor of racism in the post I replied to. I quote: "It got to the point where we [...] discussed it and concluded you were just racist". To accuse a professor semi-anonymously of racism is completely outrageous, so yes, I ridiculed him for that. Especially when absolutely no evidence of potential racism is provided. Careers are destroyed over baseless accusations of racism, y'know.
Note also that the student is extremely condescending. His opening insinuates that the professor doesn't know the difference between correlation and causation, which is ludicrous. The student concludes with "And that, Panos, is where you failed". Again, unnecessarily condescending.
