Anyone ever noticed the anti-white southern man on the “Heat of the Night” tv show?

I’ve been spending time with my father and he’s been watching a lot of heat of the night episodes and I can’t help but notice that every bad guy is 99% a white man and always has a confederate flag located somewhere either in their jeep truck or house… lol They make a poor southerners seem like the most racist despicable people on earth…
I try to tell my father the many races celebrate confederacy. Black celebrate the confederacy Brazilians have a huge celebration every year, people that served in the confederacy were Asians Indians Latinos blacks…
why do TV producers produce such garbage? Divides us so much
