Heh, I get down votes from both sides a fair bit. In one part I am supportive of views, but raise obvious issues in other areas. This makes the For team upset. The Against team hates me too because my stance is on the For team's side. The result is an inbox full of fine examples of how in-fighting destroys the grass while the other side of the fence has no idea they're apathetically winning.

Almost all of this comes down to people attempting to express their self-assessed virtuosity as superior to others, or they are driven by a manipulative fallacy—argumentun ad populum is a big one in echo chambers—causing them to easily sway closer to extremes with little critical thought first.

This is why we are supposed to discuss and not argue, remaining constantly open to exploring and contemplating new information. It is not about who is right or wrong, rather the discourse and learning from it. But that's not the default setting in many Lemmy communities.
