Apart from enjoying the lexicographic properties of Katy Perry’s (perfectly understandable!) use of the euphemism “interesting” here, I’m really not sure what’s so difficult to understand about her explanation of her GaGa criticism, or her original “Alejandro” critique. It’s no secret Perry’s pre-history includes a career as a Christian pop singer, and why should we be surprised that someone religious enough to start her career by making religious music should have a low opinion of blasphemy?
It seems this is a case of the majority of American Christians (78 per cent of the population) stereotyping the beliefs of the minority of American Christians that are involved in exclusionary* Christian culture. (And that minority is what? Evangelicals and/or some varieties of Protestant?)
Mainstream America tends to think of this culture as conservative, because it often is. I suppose we assume, therefore, that because Perry’s music makes references to things exclusionary Christian culture does not usually approve of, such as lesbianism, unbridled sexuality, and moderate hedonism, that Perry is no longer a Christian. Which makes no sense; surely it is more logical to believe she is a Christian who is fine with lesbianism, sex, and enjoying herself. There are many Christians who are fine with those things. That doesn’t mean she will be fine with treating the semiotics of her religion so trivially, particularly if she’s from a specific religious background that places a lot of value on those semiotics.
I guess the interesting part is the awkwardness of the explanation she offers here. What she evidently thought was a straightforward critique turned out to be not as straightforward as she thought it was.
EDIT: Pretty sure “semiotics of Christianity” is not what I’m trying to say. I meant “this video has stuff I can quite understand Christians like Katy Perry getting mad about” without saying stuff like “people who are serious about their Christianity” because there are plenty of ways to be serious about Christianity, and getting mad about GaGa videos is just one.
*I’m not comfortable with that term, but I think it accurately conveys the actively non-secular nature of this culture. Of course, they would very much insist that the culture is inclusive, in that it includes all who are interested.
