Interesting – I do like being able to use capitalization as a way to distinguish what kind of “ID” a person is talking about, but I can also see why, for those who see little distinction between the mere idea of intelligent design and “ID Theory,” blurring of the lines would not seem such a problem as it might for those who see a stronger difference. I don’t really discuss it much so I haven’t paid much attention to how it’s used in more casual discourse, but the use of the acronym ID may blur this more, since a capitalized acronym does not necessarily denote a capitalized phrase.
