Can There Truly Be An "Internal Critique" Based Upon the Presuppositional Approach to Apologetics?

Paul Manta replied, in part, to my previous post (below) by saying, “A Muslim could try to make the [same presuppositional] argument, and I would hope that he would. But making the argument doesn't mean that it'll fly. So, we must subject each worldview to an internal critique, like I did….”

An “internal critique” is what is asked for, eh? And Paul did this internal critique of Islam in the link he provided eh,? So why don’t Muslims just abandon their faith after reading what Paul wrote? Why? Why don’t they accept his “internal critique” and deny their faith? Isn’t it because every world-view has Kuhnsian anomalies to it that the believer accepts despite the difficulties? And with that being acknowledged from his presuppositional approach, then there can be no real internal critique to someone else’s faith.

I believe I am critiquing Christianity internally here, here, here,here, here, here, and here, to list a few of my previous posts. There will be more to come. But I can see Paul is no more impressed with my “internal critique” of his faith than Muslims are with his “internal critique” of their faith.

Just to say that an internal critique of the Muslim faith is what a presupposionalist does (i.e., negative cultic apologetics), doesn’t solve much of anything. Why? Because Paul is still doing his critique from a different presupposed perspective other than the one he’s critiquing internally. Paul’s whole apologetical appraoch presupposes there is no common ground between the faiths he rejects, and hence, differing world-views and religions are incommensurable.

Therefore, Paul isn’t truly accepting, for the sake of his critique, the whole world-view which he wants to internally critique. If he did, then according to the same presuppositional apologetical approach that he advocates, he would be a Muslim. Why? Because every faith has internally inconsistent anomalies to it that poses problems to the adherent’s faith, but that faith is presupposed and believed despite the anomalies.
