I don't disagree with what you wrote, but as far as 4chan has developed a style/brand, the tone of the page felt surprisingly non-edgy to me. Anons usually aren't known for unironically repeating media slogans, are they? ("Abortion is a human right!")
The mudkipz catchphrase was also very forced. Reminded me of the "hello fellow young people" meme. Of course, it might all be intentional.
