see for yourself, use any instance that doesn’t wholesale de-federate with any other instances. you’ll see that any post that has a pejorative tilt on liberal leaders or causes (especially biden and gaza) will have majority downvotes; resulting in little to no engagement; while similar posts anywhere else on the lemmyverse have active discussions and mixed voting.

lemmy.world is the best example of this.

seeing the down votes on this and other posts on quality content makes me think that the lemmy.word-er liberal infestation is spreading to the rest of the lemmyverse.
