Why do we as developers feel a need to constantly trash the things we don't like? If you don't like something, don't use it. Talk about the things you do like instead.
Some folks will just use a language without thinking about its downsides. If you use language X for a long period of time, you can become blind to areas where it is wasting your time.
Again, I do agree that the tone could often be much more civil, but I would hate for experienced programmers to stop pointing out things that bother them about their programming languages. Much of the time it is not just about personal taste -- it is about real problems with the language that have a real cost.
But that's not what this article is, and I think we all know the tendency I'm talking about for people to spend more energy and feel more comfortable trashing things than talking about what they like.
Maybe the discussion will identify some problems with a thing. There's an infamous piece "PHP is a fractal of bad design" that I found very insightful.
But, honestly, it's mostly because it's entertaining.
