We are discussing in a thread about the political compass, so even strictly going by the meaning of the word “centrist” it wouldn’t put you only on one axis in the authoritarian half.

But in reality a “centrist” is usually referring to someone in support of the status quo or at least someone that doesn’t want to rock the boat too hard. Where exactly that person falls in the ideological spectrum can vary widely between countries, and even if they are not outright conservative in their expressed opinions, the very act of preferring the status quo makes them structurally conservative.
