Here are excerpts of my transcription of Matt's video, which is titled "How to Talk to Christians":
Hi, my name is Matt Slick and welcome to the CARM Answer Desk. I want to discuss the issue of Christians and how they attack atheists and atheism. [snip] I'm gonna give you some pointers on how to deal with some Christians, OK? Atheists, listen to this. Look, we know that the Christians are constantly attacking atheism and attacking what we have to say. Well, I'm gonna tell you some basic, basic stuff that you can do to deal with them, all right?
Let's say for example a Christian makes an assertion. I'm gonna give an overly simplified one. You know, they'll say something like, "There is a god." OK, you know what? Instead of saying "Oh no there's not!" and then trying to prove it, I would say to them something like, "Well, how do you know that?" Ask questions! If they make an assertion, have them substantiate their assertion. Very, very simple. Have them establish what it is they're saying. [snip]
Remember this, don't try and just simply refute whatever they say whenever they say it. I'm known for saying this great comeback when a Christian says something to me. They'll say something like, "Well, atheists are really arrogant," and I'll say something like "So? What's the big deal about it? If you don't like us, OK, whatever." And the Christians, you know, what are they gonna do? [snip]
So, when a Christian is talking to you, ask those questions, and...seriously, [say] "Yeah, so, what's the big deal about it?" Get them to explain more. And the more they do that, then the more you're gonna find out that they're gonna have holes in their ideas and holes in their statements. It's not that difficult to do. [snip]
Now, I'd also say that what you need to do is admit—this is important, atheists!—admit when you don't have an answer. You know, if I were a Christian and I was talking to some atheist and this atheist was trying to snow me, and trying to give an answer for every single thing, and the answers are falling apart, I'm not gonna have any respect for that person. But I'd have a lot more respect for someone who said, "You know what, that's a good question. I'm not really sure; let me go research it for you and get back with you." That's not a problem, that's intellectually honest, and you know, I do that. You can do that, and you know what, even when Christians do that, I appreciate that when I'm talking to them, and I ask them a question, and they don't have an answer, and they say, "Well, you know what? That's a good question! I'll have to go back and research it." No problem at all. And then just follow up and do that.
So basically, dealing with Christians isn't that difficult. They're the ones who often make assertions. Ask them to demonstrate the validity of their assertions. Listen to what they're saying. Ask questions about what they're saying. See if their statements are logical, see if there's some problem inside the logic. For example, what if a Christian said, "There is a god, I know there is a god," you'd have to know all things to know if there is or is no god, so logically it's not possible. So by listening to what they say, you can hopefully learn a little bit about logic in their statements and see if their statements are valid or not. It's not that difficult; it's pretty easy. So basically, ask questions, listen, find out their presuppositions, admit if you don't have an answer, and learn to say "So?" a lot. See how it goes, and I think you might enjoy your discussions with Christians a lot more.
My only quibble with Matt's video is that he was a bit careless with his wording (that's been going around lately). I think he got the terms "atheist" and "atheism" confused with "Christian" and "Christianity," so I took the liberty of fixing that for him. Oh, and where he said things like "there is no god," I fixed that too, by changing it to "there is a god." Other than that, good job, Matt!
By the way, "CARM," which Matt referred to at the beginning of his video, is the acronym for the Christian Apologetics & Research Ministry.
On the off chance that Matt might take issue with my...ahem...corrections, here's his video, with his original wording. See which version you prefer, his or mine!
