I had to Google the Blub Paradox (https://en.wikipedia.org/wiki/Paul_Graham_%28computer_progra...) but I see what you mean. It's based on the idea that someone who disagrees with you about something can't be acting rationally, rather that they are somehow incapable of perceiving your wisdom. Sometimes that is the case, of course, but I don't think that explains why Lisp isn't the universal language that everyone writes everything in.

I have a lot of warm fuzzy feelings about Lisp as well, but a lot of Lisp advocacy has been of the "One True Language" variety as opposed to "right tools for the right job, and here's why Lisp might be the right tool for you". It doesn't affect my perception of Lisp, but it doesn't help market it either.
