My experience is the opposite, I've only met incredibly friendly and helpful people within the functional world.
Your description of a person who has to put down everyone else in other to raise himself up, is just person with such low self-esteem that it's become toxic. You'll find these people everywhere, it's not exclusive to FP.
I'm personally fairly rigid about implementing business logic as functionally as possible, but I also enjoy game development which is inherently stateful and never without some imperative parts. I do think FP has some advantages over Imperative programming in many instances, but the opposite is also true, and I'd never pretend to be smarter or better than someone like John Carmack, who's made his career almost exclusively in Imperative languages.
