How many can tolerate the obvious truth, supported by thousands of studies, that average differences in intelligence across the various peoples of the world and especially races are due to genetic factors?
Interesting question. The TV tells that evolution exists but race differences (especially in morality, behaviour and intelligence) don't exist. But evolution requires race differences - what now?
Also the TV admits that race differences exists for things that are too obvious to deny (like appearance, body size, blood pressure, testosterone levels, etc.) but deny any differences for things that may have been tested and confirmed countless times but are touching on the subject of what makes us human and what distinguishes us from animals (intelligence, behavior, morality, etc.). Essentially the TV claims that evolution works on the human body, but not on the human brain.
People who are raised by the TV (and there are a lot of those) actually believe these contradictions, it is what Orwell called "doublethink".
