The reason why Haskell still doesn't really break through in the corporate world is not a failure of arrogance, but a marketing failure in the strictest sense of the word 'marketing'—which means prioritizing the right features to target the right market.

A large proportion of the talk linked below is based on the book “Crossing the Chasm".

The book was originally written for startups trying to break into the mainstream, and this talk adopts that book to programming laguage (or tools more generally), particularly regarding Haskell.

Gabriel also suggests that in order to "cross the chasm" you have to offer a best-in-class experience in some area, and suggests that Haskellers adapt the language to facilitating building interpreters, which is it particularly well suited for.

So, base on the above, I don't think the OP's emphasis on the emotional analysis of Haskell programmers is anything more than the OP's just-so story, although the notion of parochialism may have some crossover with the concept of marketing.
