Are we doing CMVs, now? Cmv - there is little epistemic value to internal critiques.

I think we all want the strongest positions when debating or discussing with theists, and perhaps I'm wrong here but I don't see genuine value in taking on the theists worldview in order to show contradictions within it.

The majority of Christians I see will engage in cognitive dissonance to resolve the contradiction and if that is not viable they may appeal to a god that allows contradictions.

I feel like once we allow magic into the debate we are just arguing lore in a story that has few constraints, rather than using the epistemic warrant gained by years of scientific inquiry, philosophy and common human introspection.

This isn't a super eloquent post, I know, and I guess my genuine question is that fighting theists on their own grounds genuinely seems fruitless to me, and I am wondering why this technique is employed so often.

Lastly, I grew up baptist, and within the baptist worldview if I assume that it is true, there is nothing that could be said within an internal critique that would demonstrate this false. For example I would assume that individuals would attempt to attack the tri Omni, and I believe atheists get mired granting these qualities and attempting to show a contradiction, which again is getting into the weeds and giving up our epistemic high ground which is that these claims do not have warrant.

So, can anyone change my view that internal critiques are discourse strategies we should shy away from? Or is there some reason or circumstance where they can be useful?

Thanks for reading thus far.
