I very rarely came across rude or disrespectful people. I don't know how I slipped by all of them but I honestly can't think of one experience off the top of my head that was like that. I'm sure they're there but I'd have to think really hard to recall them.
Often times when you face such an overwhelming challenge as global climate change it can be somewhat daunting - it's kind of like trying to lose weight which I know something about.
