Whatever those logical laws are, those logical laws must, then, be those logical laws, whatever they are. So our 'normal' kind of logic must also apply even if there are somehow also "other" kinds.
This comes down to Universal Idealism or Universal Realism. I generally accept Universal Idealism but I would accept one form of Universal Realism: I am quite happy to say that "Redness" exists for example, if I am to say that "Redness" is merely the totality of all things that are Red. And I can use this the same way with logic.
