I think this is a problem with Lisp people. Lisp is a good language, but their users are too emotional about it. They always think in terms or loving or hating it.

I don't like, for example, reading Lisp books where half of the time is spent on selling the language: why it is the best thing since sliced bread and all.

Just let the features talk by themselves. Nobody needs to be indoctrinated into liking a language. Anyway, at the end, emotions are not gonna decide what language is used in a project.
