In this group, my friends are all former C programmers, not so much C++. I mean one does what one has to. I think I'm the main Lisp fan, and no Haskell or anything (although I went to high school with a guy that loves Haskell and lazy eval and mathematics of infinite sequences made fully instantiated). I think the idea of pure functions being safe in a way state mutating functions are not is deeply appreciated by C programmers.
In larger groups, I have never found much appreciation for functional programming, and side-effect free APIs/design philosophies to be particularly popular. Usually there's one smart person that loves it, and they make some systems that are 10x as performant as the standard Java whatever and then no one else gets it and it's rewritten into regular OO Java and the person moves on to a more enlightened job.
