I dont think it is helpful to see it as a slur. This is more like "use my words against me" and it works, really well. The right wing folks this is messing with identify as being normal, predictable, sensible, strong, etc. Not weird. So when one of them goes to a donut shop and has their internal record get stuck on "OK, good" it looks abnormal, unpredictable, nonsensical, and perhaps even weak. AKA weird, and we can make them uncomfortable with that.
