[below an IRONY ONLY sign, at a desk showing a dog about to be kicked, a yellow character reassures us]
Don't worry, it's all irony!
Here at the ironic dog kicker club we are just pretending to be dog kickers in order to mock real dog kickers
[a huge sign reads]
ONE YEAR LATER
[lots of different characters are shown smirking while kicking dogs, trash is all over the place]
Kick!
Pow!
Heheheheh
Totally ironic I swear
I love kicking dogs
Boomshaka
Yeah wreck those doggos
Kicky the doggy
[a character which looks suspiciously like the one in the first panel but sideways shrugs above a LIVE ANONYMOUS NARRATOR REACTION]
Wow, unexpected!

We take irony very seriously. If exposed to irony, immediately quarantine yourself and consume only sincere media until symptoms subside. Side effects of prolonged ironic exposure include accidentally cultivating the exact audience you claimed to be mocking, saying "based" unironically, and waking up one day to discover your community is now 95% composed of the people you insisted it was making fun of.
If you or a loved one has accidentally founded an ironic community, remain calm. Seek immediate assistance from your nearest licensed grass toucher and begin a strict twelve week rehabilitation program consisting of sane hobbies, sunlight exposure, and conversations that aren't buried under multiple layers of snark.
Together, we can build a blander tomorrow.
I think it's trying to be meta-commentay, utilizing diagetic irony as a form of meta-irony. At least that's the only reading that really coherently parses. Ironic spaces/jokes have always been infiltrated by those who genuinely hold those beliefs, it's basically impossible to defend against, the kinds of things you would want to make fun of via irony are almost always held by those who are unable to understand more than surface level interpretation of media more generally.
The thesis is probably better read as "fuck it we ball" and refusing to let go of irony just because supider people misunderstand it.
I deeply appreciate your use of the word "diagetic", excellent word usage
