To this day, my favorite argument I ever had was with my Nascar-loving family about how a thin blue line flag on a Nascar is antithetical to the core tenets of Nascar.
There is no organization more rooted in ACAB than Nascar. Literally, the only reason it exists was that a bunch of moonshining families had to build cars that could outrun the cops while on supply runs during the Prohibition Era. The goal was to make the car look like a regular vehicle so they could pick up supplies or drop off illegal alcohol without arousing suspicion. But if the cops were on you all you had to do was put the pedal to the metal and that little truck could outrun them with no problems.
And of course, families would be in competition over who made the best alcohol, and whose car was fastest. So, they would have races on the weekends. When prohibition was lifted, the races continued. And that is why we have Nascar.
It really frustrates me how people look at American car culture and scoff at it. Formula One racing is more exciting and more dynamic to watch, but the history of it is not as interesting: a bunch of rich assholes who made specialized cars for racing. And to this day, it is still a rich man's sport. Whereas Nascar was about a bunch of so-called hicks in the backwoods who used some basic hand tools and trial and error to make a junker into a racecar.
