Centrists by and large are ideological cowards Why? They just have beliefs that put them in the center of the left/right dichotomy. Is one a coward for not being polarized? This point is almost moot, though — centrism is rather nebulous and ephemeral.

Because it is the mechanism centrists use to arrive at their political beliefs that is cowardly. They don’t tend to start from a perspective that arises from their empathy and curiosity for the world and build their politics based on that, they look at the spread of opinions people have around them and just go right down the middle where they can disappear into the crowd without having to do the hard work of creating an actually ideologically rigorous belief system that adheres to reality and evolves with it.

A rightwing fascist emphatically cheers on the genocide of Palestinians (and Jews for that matter confusingly), a leftist emphatically declares genocide is a wrong and a human rights violation. One of those is a dangerous world view that needs to be resisted with force and the other is a world view of harm reduction and solidarity with all humans. What makes most centrists so cowardly is that they take both of those viewpoints as reasonable starting positions and average them to emphatically supporting "some genocide!" and it is incredibly pathetic.
