There's a subreddit that lists news stories of self-defence situations with a firearm. They don't make the news because they are all local stories but it happens all the time.
The idea that the US can somehow turn back the clock with hundreds of millions of legal guns already purchased is laughable. Almost every attempt at the state or city level has completely backfired. That train passed long ago. And the denial of this has only ever worsened the problem. I'd go as far as saying it's an anti-science position in 2020.
An aggregator of stories on a given topic can make anything seem to happen frequently. This would, by design, ignore any stories that don't fit the narrative. It may be a good source for stories on that exact topic, but is by no means an accurate indicator of frequency, especially as a sole source.
Unless you correct for education, wealth distribution and Asher things like gang affiliations that's be selection bias too; there's just much more than "firearms deaths/firearms ownership" going on.
