I know nothing of the American Interest in particular. But there is nothing wrong with particular publications having particular philosphical starting points. First, an author's analysis is usually more incisive if she has a clear personal thesis. Secondly, the reader is better prepared if she knows the biases of the writer.

We can't expect to read articles as if they are the neutral truth (which doesn't exist anyway). That's why we need a free press expressing a diverse bunch of ideas.
