And which will frequently be completely wrong, but they will believe it absolutely because it fits with their political biases.

… as well as the shooter’s posting history and maybe a link to the livestream?

Respectfully, you also said that "we now know" that taking the COVID19 vaccine could have killed you earlier today, which is completely false. I don't think you are getting your news from reliable sources, and I see this comment as further evidence of that. I'm sure there's lots of information on 4chan about the identity of mass shooters, and that some of it is accurate, but most of it is probably wild speculation, outright trolling, and mistaken identity. Like when Reddit pinned the Boston Marathon bombings on a series of innocent people who were standing on a rooftop or missing because they had killed themselves.

Then again, you also openly expressed an antisemitic conspiracy theory (https://news.ycombinator.com/item?id=46959252) along with a lot of racist Great Replacement stuff (https://news.ycombinator.com/item?id=46922014), so maybe unreliable news sources are the least of it. Seems like you're probably a literal White Nationalist.
