Reformed Apologetics: Defunct and Disillusioned

I chanced across an interesting post by Mark (tartanarmy) at the Unchained Radio forums. In a thread discussing whether atheists could comprehend absolute truth, he burst out with the following:

I don't see how we can communicate with Atheists. How does that work? I know “evidentialism” is an inferior type of apologetic argument, but is not the presup stuff useless too?
I mean, with the “noetic” effects and all, where does it lead us?

I can see his point. If you assume that everyone who disagrees with you is necessarily mentally handicapped, what's the point of evangelizing? Well... because God tells them to, apparently.

I think we should just believe in scripture, quote it, and leave the results in God's hands.
I also believe we need to get involved, interact with these guys and just be a witness to them as much as is possible, that they may come to be convicted and own their sin.

I'm not sure how "being a witness" is supposed to help. Supposedly, hearing the Gospel message is all it takes to cause conviction.

Am I way off beam here, or what?
I know the TAG and other well thought out stuff makes them look stupid, but what’s the point? We know that already from scripture before we even engage them.

I don't think I need to comment on the idea of the TAG being classified as "well thought out."

Help me understand. I keep waiting to see them reduced to the point where they kind of get it, but it never happens. I keep waiting to see if they then try to defend their position from an internal critique of it, but it never happens, nor do they ever even seem remotely interested in finding out how we critique other kinds of religious beliefs.

I am a bit disillusioned. Please give me some advice about this?
Dustin?, Gene? Paul? What say you fine guys?

If I could offer some input- maybe the reason why we atheists aren't "reduced" to Christianity is because we actually have some good reasons for rejecting Christian claims. I know this is hard to accept and understand when you have to assume that atheists don't exist in the first place, but such is your travail.

I kinda feel sorry for the guy. It makes me think of someone in a mental hospital, depressed, and saying, "What's the point of even trying to muster the troops if nobody in here believes I'm actually Napoleon?"
