I've noticed the same thing. It's a curious pitfall of insisting that Christ is Lord of everything and then getting your categories for everything from a non-Christian source, or assuming that lordship is undifferentiated, or both.
For instance, if Christ is lord of the mind in an undifferentiated way, then Christ is Lord of any academic field. And then we've subtly snuck the most absurdly illegitimate of pseudo-intellectual disciplines under the aegis of Christ's name. It's important to understand that Christ is Lord of some things in order to destroy them (such as lies).
