Don't know of such a filter. But did you know that that is the primary function of Lemmy? It is a link aggregator first and foremost. Everything else stems from that.
When it comes to news, I already know that very few possible events would have facts that were notable enough to change how I feel overall about the topic/event.
But, since I intentionally consume way less news than I used to, other than some Jon or John clips, I read my news.
Any fact finding I end up doing it just a hodgepodge of finding what I can through search, relying on primary sources where possible obviously.
So, when it comes to news, reddit was, and Lemmy is the place I go to be aware of events that I'd see if I watched legacy media / social media. And to just vent and maybe learn something.
I'm a title only kind of gal these days. Anything more, and I'd end up as a headline myself in short time.
Fair enough. My main reason for joining was to scroll through memes and engage with fan communities I'm part of. I used to have a reddit account a long time ago, but I left, and recently tried to make an account again, only to discover what a clusterf*** things have become, which sent me running here after weird stuff started happening with my new account.
Definitely search for the communities you are interested in and click subscribe. There may be several similar communities on different Lemmy instances with different rules or vibes. Also, if the subscribe button says subscribe pending, you can ignore that.
Lemmy is amazing to be a "knight of new" as it were because the cross-talk, noise, bots, etc are just not there like they are in reddit. I've found communities I never would have known about.
Keep in mind Lemmy is very actively developed. If you do end up staying with Lemmy consider tossing a few dollars to the devs. I've always found the devs courteous and approachable when I've encountered a bug.
