not him but there's no need to overinterpret what he said just to make a blatant statement.
there's a reason why monogatari is a "you love it or you hate it " - series. there's no middle ground bc it's completely one dimensional into one specific niche. that's why there's a lot of diehard fans and a ton of haters.
also he's just ranting about the shit taste /a/ has, which was proven more than a thousand times and is also reasonable.
the one being self centered is rather you than him.
