First it was Ian Smith, now Kerrie with the PMs giving me warnings. I thought this forum supported academic freedom. I guess I was wrong. I hope no one on the administration team here ever criticizes the society of the past for persecuting intellectuals like Galileo, Copernicus, and Socrates for being polically incorrect, for that would be hypocritical. Ironically, Ian Smith made the comment "Yeah but you need to understand the past and the mistake made during that time to make sure that mistake are not repeated in the future" https://www.physicsforums.com/showthread.php?t=62323 Cheers!
