False dichotomy. Strawman. Just because someone is centrist doesn't mean they don't know what to think. It usually means they have a nuanced position on an issue that doesn't conveniently fit into a box that is red or blue.
All the people I know who like to think about issues deeply generally hate to be described as left or right and much prefer to reject labels. Sometimes I'm not sure they actually can't be labelled, and sometimes the difficulty in labelling them comes from an overall lack of coherency rather than a truly uncategorisable position, but, I don't know anyone who calls themselves a centrist and could talk about politics in…
I would definitively not call myself a centrist, nor left or right. There is some good goals even in the far left and far right, but also a lot of things I strongly disagree with to the point of alienation. Centrism simply just an other political agenda with its own set of prioritized demographics and intentions.
