Well my gripe is with degradation - stuff such as alternate for alternative, or the terminal blurring of uninterested and disinterested. I don't think we necessarily have to reserve litany for churchy use. It's perfectly good in that context, but the more modern expansion into tedious lists of things (it's already acquired that nuance of tediousness when it's used that way: "I don't want to hear your litany of complaints...") is colourful. What's more, it doesn't degrade the liturgical context for the word. So it's fine by me!
