Look at the hive, the religious symbolism there is huge; they have temples, they are often seen genuflecting in worship, hell take a good look at a wizard and try telling me it doesnt bear a passing resemblance to a cardinal or some such high ranking catholic priest. Then you have the Vex and their worship of whatever the hell that thing in the black garden is. I suppose one could argue that the religious overtones of the traveler + the speaker mitigate all the negativity that the hive and the vex bring, but overall religion (or at least its more aggressive side) takes an absolute battering, as is rather usual in games nowadays.
