Question

In this excerpt from "Totally like whatever, you know?" the speaker alters the syntax of his statement for what purpose?

"I have nothing personally invested in my own opinions, okay?
I'm just inviting you to join me in my uncertainty?
What has happened to our conviction?"

The speaker is not inarticulate, as he pretends to be, and now he offers evidence of his ability to speak with conviction.
The speaker is not convicted about this unconventional manner of speaking, and he sees no reason to continue with speaking this way.
The speaker does not have a strong command of the language, and he does not know how to use punctuation.
The speaker cannot appear uncool to his audience, and he tries to quickly redeem himself.
