No, other than the fact that the HN audience is largely western and the Catholic Church has had much more cultural influence in western society than any Islamic institution has.

Not at all. Feel free to find the MuslimLife equivalent of this article and I'd be betting to wager the OP would say the same about them.

Let's not act like he wasn't spot on, either, though.

Spot on in what way? That the criticism is invalid because of the religion held by the people making the criticism?

No. It's more like the hypocrisy of schools making a criticism on banks for raising their rates.

I think the implication is that the criticism may be valid, but that there is hypocrisy involved wrt author - i.e it's not really about the criticism, but the author/religion.

I'm also guessing it was tongue-in-check.
