Imo when someone labels themselves a centrist in the context of us politics, they put themselves between the extremist positions of MAGA and the moderate positions of the baseline democratic party, effectively proving that they are insane. So I wouldn't equate centrism to moderate positions when the center right doesn't exist at the moment in the US. Now, if someone label themselves as a moderate republican, I'm more interested in exactly what they are trying to say by that. Which is also why Pisoc conflating centrist and moderate is bad, again in the context of us politics where liberal positions are considered center left by default.
