Answer and explanation:
The purpose of using dashes in this excerpt is to set off an appositive sentence that contains commas. An appositive sentence is a structure that offers further information on something mentioned before it.

In the excerpt we are studying here, the appositive "-so-called because they used to, like, DECLARE things to be true, okay, as opposed to other things are, like, totally, you know, not-" is a very long one and full of commas. It is supposed to offer further information on what declarative sentences are.
