A centrist makes up their mind based on the merits of the topic, not based on opinions from the left or the right. A centrist isn't someone who says "both sides have a point."
So I'm not sure what this comic has to do with centrists.
A centrist isn’t someone who says “both sides have a point.”
A centrist should say "both sides have a point", but they should not stop there - they should critically review these points to decide which ones are stronger and more correct on a case-by-case basis.
Something tells me those that call themselves centrists, don't always subscribe to the actual definition of centrism. But in praxis, centrists share a status quo mentality, which means they're pro-capitalism, which means they side with the political right on most issues.
