> It's not a joke if you repeat it 100 times.

A joke does not stop being a joke because of how often it’s repeated. You may no longer find it funny, but it’s still a joke. More importantly, it’s still satire, and The Onion is a satirical news website.

> That article has some real "The best thing about school shootings is we get to have literally every article on our website be this clever headline we wrote 10 years" energy to it.

If that’s what you take from it, you have completely missed the point. The headline works because it’s social commentary, being funny is secondary. The fact they keep reposting it over and over is itself part of the criticism, it shows disapproval for an easy resolvable situation and removes teeth from the arguments of those opposed to it.
