I don't have a lot of respect for pedestrian fears like fear of heights because the only reason they can continue existing is because people nurture them. They're fears that are very confined and so aren't typically disruptive enough to someone's life where they absolutely need to do something about it. All they have to do is restrict their lifestyle and just keep avoiding situations that involve heights in perpetuity, e.g. mountain hiking, rock climbing, rollercoasters, ferris wheel, checking out the view on top of a skyscraper, etc. If they're so weak they can't even confront a small, circumscribed fear like that, it doesn't bode well for their ability to cope with much more traumatic situations in life.
