You're better off asking somewhere where actual centrists congregate, rather than Lemmy where there essentially only different flavours of left-wing.

But critical to any understanding of this topic is that the terms are all relative. There's no "true" centre just like there's no "true" left or right - these terms only make sense in relation to each other and to established norms. A centrist is therefore someone who has views that are somewhat in the middle of mainstream politics for their context.

Leftism has always suffered from a lot of internal division and purity testing, so when you ask in a very left-wing space like Lemmy, centrists will always be accused of being right-wing, but so will anyone who isn't a raging communist - they've failed the test so they're with the others - the right-wingers.
