As I said, I think "Invisible to Gaydar" would be considered offensive for much the same reason. It legitimizes the stereotypical association between camp and gay. It suggests that campiness is usually a reliable indicator of sexuality, aside from a few bizarre outliers. That, I think, is what's offensive about it.
