Just like the Roseanne Show (or now The Conners) .........
Dr Phil is just another attempt at conditioning of the American people of all backgrounds to normalize and standardize working class white culture and a subtle attempt to legitimize White male intolerance.
This has been going on since "All In The Family" back in the 70s.
In Dr. Phil, here you have a big Caucasian man with a strong southern drawl who often prides himself in being a "straight talker" and "tough lover" and at the end of the day he apparently knows how to "solve" everyone's problems.
No matter what the subject of these shows are, the MAIN and constant theme is that being "politically correct" is the enemy and the big rude White man is really the "good guy". So when you see big White men being rude and politically incorrect (i.e. unapologetically racist) then instead of being repulsed by it you accept it as someone being "down home" or sincere and endearing.
