No, the people who frequent communities tend to upvote/downvote more. On the collective level that results in the stuff people in that community want to see drifting to the top, and the stuff they don't want to see drifting to the bottom. That filters out a lot of bullshit and makes the user experience better.
It's not like algorithms are being manipulated to promote a profit motive or political agenda, or amplify an in-group while marginalizing out-groups, the way corporate social media does.
It's just an organic filtering based on what the community members as a collective do or don't want to see.
If you don't like the vibe of one community, go find a different one or start your own. Telling people to stop downvoting you is just petulant.
