I'd guess most voting come from people browsing all communities. That's how I found your post.
Progressive Politics, Gun Control, Single Payer Healthcare and Free Abortions for All!
We like leftists and liberals.
We want to ban all guns.
We want free healthcare.
We want UBI.
We don't mind being taxed.
We want to give everyone a free abortion!
Everything isn't downvoted. Sort this community by upvotes and you'll see there are a handful that are positive. You can do the same with the people who post here. Go to their history and sort by most positive. All of them have positive comments and posts.
It's the content that's being downvoted. Not the community or the users.
I downvote posts if they're idiotic.
Communities about idiotic ideologies tend to attract idiotic posts.
Because conservatism is a dog whistle for cartoon villainry.
I did a quick scan and the more misleading and fear mongering posts are downvoted, the news type posts seem upvoted.
Maybe be specific in asking which posts you're concerned about getting down votes? Otherwise I'm going with my general answer here.
Because lemmy is small, so the natural brigading that comes from everyone being able to see all the posts means smaller/unpopular communities will have these natural downvote noise. I see this in monero, linus tech tips, communities all the time. There are people with a axe to grind, and rather then blocking a community they just want to be negative. it brings them joy, so be it.
Lemmy would benefit from community tools, like requiring participation before votes count, or posting karma, etc.
Growing small communities should be a priority for lemmy
They hate you and want you to die.
