Exclusiveness of this kind does suggest a condition or mental state everyone is anxious to distance themselves from.

If nobody is willing to admit to suffering from this condition or mental state, might it perhaps be that nobody does?

I've made my own position very clear: "I know from experience that traditional music is likely to interest me and that singer-songwriter work is likely to bore me. Some traditional performances are arse-achingly boring, and some singer-songwriters are stunning, but (for me) the balance of interest vs boredom is mostly the other way round."

Of course, I also like loads of music that can't be described as either 'traditional' or 'singer-songwriter'.
