I think the article is leaning more against the rabid atheists. At least most of his examples he says that piss him off are Atheists, rather than Religious people. Regardless he makes some good points.
1. You Can Do Terrible Things in the Name of Either One
Yes, you surely can. Of course that topic needs more discussion but he just says that this statement is right. And it is.
As for this quote
"And can we further admit it's actually physically impossible to calculate whether, if your side had its way, the volume of terrible things happening would go up, or down, or stay the same? I know you have an opinion on that, and I can guess what it is. But we don't know, and can't state it like it's fact. Right?"
Well, yes, but the old, we can't prove anything 100% now can we, is a pretty dumb approach to this, I think.
2. Both Sides Really Do Believe What They're Saying
Many, maybe even most, yes, probably.
Though I disagree with some of his reasoning and statements within that part.
3. In Everyday Life, You're Not That Different
I think he disregards quite a few schools of subjective morality as well as other reasons for objective morality in this part. I would say though that in my every day life I am probably quite similar to some Christians, just as I am different to some Atheists and vice versa.
4. There Are Good People on Both Sides
Yes, no doubt, there are people on both sides that are "good" in my opinion.
5. Your Point of View is Legitimately Offensive to Them
I guess one can argue about the word "legitimately", but yes, I would say they have their own, maybe good, reasons to be offended, like I have mine.
6. We Tend to Exaggerate About the Other Guy
Some do. Personally I don't think I do.
7. We Tend to Exaggerate About Ourselves, Too
Hmm, yes, in the heat of debate you might go to far in the opposite direction just to disagree. Though again, personally, I try not to, but of course it is not easy.
8. Focusing on Negative Examples Makes You Stupid
Not necessarily. But the whole picture is of course most important.
9. Both Sides Have Brought Good to the Table
Yes. Though I think his examples aren't the best.
10. You'll Never Harass the Other Side Out of Existence
Seems like a pretty baseless statement. Who knows, really. I agree though that other ways might be better to convince people.
