Not sure why you think it does. The post refers to two things, that some who argue religion causes bad actions seem to ignore any good actions people say they did because of religion - and I don't see where FGM deals with that.
The second is that Weinberg's quote that it takes religion to make good people commit evil is nonsense. And it is because people who appear good commit evil band cite reasons other than religion. Leaving aside the whole question pfwhether FGM has a cultural basis as well as a religious one, it wouldn't substantiate Weinberg's claim that it is religion which is capable of this as opposed to any overall belief in something such as cultural, political or tribal motivations.
Indeed as Vlad validly points out the Milgram experiment shows all you need is a lab coat and a clipboard. Though Vlad makes the same mistake as Weinberg in trying to tie the behaviour to something specific instead of noting that it appears to be a fairly generic trait.
Indeed if you look at the Stanford experiment or much of history, the idea that it takes much more than having authority for other wise 'good people' to act evilly seems a stretch.

I see where you're going with this post and I go along with you, but if you read the post you're responding to here again:
I've not been following this thread but I couldn't help thinking that somehow
F G M cuts right across this particular post of yours, I acknowledged that I hadn't been following this thread and I would have thought this would indicate that I could be missing some previously made point and I made it clear that my comment was specifically about that one particular post, just in case I my comment was misunderstood
I often assume that most intelligent people don't need to be lead by the hand and assume my, admittedly, shorthand but not that shorthand will be taken as I have stated, but then you'll always get the odd one that needs every tee crossed and i dotted before they will pretend to understand the meaning I'm trying to convey.
My working partner and I would have the occasional day where we didn't understand each other unless the English, our version, was exactly correct, that was fun I enjoyed that but sometimes that sort of thing can be
needlessly tiresome.
