> Much of Western thought traces back to serious work by Church theologians.

The problem I have with this is that it's structurally a motte-and-bailey claim. If I have to take it literally, then it's obviously true and it's simply unserious to deny it: the Church does have a pervasive influence on Western civilization. The way it's often rhetorically used, however, is in opposition and to the exclusion of other strands of thought that are equally foundational: the renaissance, the enlightenment, the revolutions of the 17th and 18th centuries, the scientific enterprise, in a smaller but still real way classical antiquity. To the extent it can be said to exist, Western civilization is a patchwork. It is beautiful and I very much like it, but I don't think any one patch gets to have all the credit.

> In fact I think atheists should make more effort to learn about the vast diversity of other faiths

A better version of myself for sure would make that effort. The problem, of course, is that other faiths are just as deep and complicated as "our own", and it would take a lot of time and effort to do so with any level of seriousness.
