Earlier quoted context omitted.
Yes, it's very cheesy, but maybe rephrase it as "people who are open to trying new languages are more open-minded by definition, and they keep a flexible mind and learn to think about problems in different ways." I mean, however cheesy some Smug Lisp Weenies(tm) may be, why not learn something new? Lisp (the language family) is really cool, you should try it. elisp may not be the most exciting family member, though.
There's a big difference between "no interest in lisp" and "no interest in learning something new."
But then you're judging something you haven't learnt yet.
Just saying... I assume you have your reasons to refuse Lisp.
