The site presents posts based on user upvotes/boosts. The bias you see is the bias of the userbase. You wanna counter it? Vote and add to discussions. You just want it magically balanced? Curate your subscribed content like hell, or use multiple different websites with different biases. Forum style sites will always lean one way or the other, because whatever gets upvoted becomes the front page and attracts like minded people when they visit.
If you wanted to ask about algorithms or if mods/admins can manipulate content then you can just ask that. Instead you asked if the platform was biased, and brought up negative trump posts as an example. Of course people thought you were upset because the dear leader was being smeared. Just ask the damn question without all the “ok but the biden stuff is just as bad and also this isn’t about politics, now lets talk about politics as an example of the bias I’m seeing”
Can you see how taking the question of “does this website allow vote manipulation by admins or have algorithms biased against certain viewpoints” and framing it around “I see a lot of negative posts about the man being indicted for an attempted coup, and that feels wrong” might give people the impression your just upset people are shitting on trump?
We know how social media works that’s why many of us are here. To avoid the algorithm rage baiting bullshit. And you walked in like “hey folks do you guys just manipulate information here? I feel like you do. Here’s a highly controversial example where I feel you are. But please don’t bring up my example, because its not about politics”
