As BoulderJohn stated, that's not necessarily common - but for those into it, there's many places to go. The biggest mistake is to make crass assumptions based on what you don't know, or have never seen, and then proclaim those assumptions and look foolish.
I have ample respect for cave pioneers doing cutting edge, extreme deep or duration exploration... . but these pot-bellied, desk dwelling, weekender cavers who chug around in clear, wide passages that get more traffic than a mall escalator... shouldn't really get judgemental based on self-awarded delusions of grandeur.
