Oh, just thinking in terms of what kinds of shitty people wind up in which breed communities? Cattle dogs have a big old "rural, blue-collar, masculine, Western" association in the US, and one that tends to skew white at that: in some ways, they otherwise occupy a similar niche to pit bulls, but one that is pretty white-coded. This is a comforting kind of image for shitty right-wing people to pick up, especially if they want to be perceived as super masculine. Right-wingers often adopt the mythos of working-class rural people even if they're actually much more urban and affluent than that, partly to cloak how much they suck billionaire dick. They're the kind of dog I could see a Texas GOP politician on a campaign trail picking up if he wanted to engage in a particularly cynical kind of ploy.
It's not that this kind of stuff is everywhere in ACDs, but it's always worth keeping in mind what kinds of people are drawn to the "image" any given breed puts out, including the shittier kinds. (Honestly, implicit in that comment's context, talking to @doberbutts who has frequently discussed the tendency for Nazis to be drawn to Dobes, was the comparison to his breed communities' own brand of shitty people.)
