Lemmy is a federation of servers. “Lemmy” is not one political group with one viewpoint. If you’re looking for different viewpoints, try different groups, or different servers.
In another comment you said this about the comments you read:
they’re made in bad faith
I don’t think this is true. I think that what you think is “bad faith” is actually “people who disagree with me”. So far, most users of Lemmy appear to trend politically left by American standards, but that’s only because American standards are so absurdly skewed to the right that it appears to stand out. By American standards, “truth” is left-wing.
