How do you mean?
I hate to say this, but the worst thing about stereotypes is they tend to be based on something real. Nobody thinks you're not going to get mugged by a Buddhist Monk in Nepal for no reason. Nobody mistakes Mafioso for Rhodes Scholars just because they don't feel like it.
Well the rumors are true, that isn't makeup and guys putting on an extra 70 lb a lá DeNiro just to play a one day role. That really is Trump's main base. They live in a certain area of the United States, and share a genealogy that can be traced back to their penal colony ancestry shipped off from England. The culture is so ingrained, some researchers actually wonder if there's actually a genetic component. For centuries they've been low achievers, less likely to seek higher education, be employed, and are given to criminality and violent behavior. They're the ones that people refer to when they talk about gun culture. If you look at YouTube videos of people interviewing MAGAs online for a Trump rally or a gun show, that's what you see. Those guys.
