I believe that Steve Yegge got it right in https://plus.google.com/110981030061712822816/posts/KaSKeg4v... and it is all about your political leaning. Or more precisely, it is about how much ceremony you are willing to go through for some promised benefit. If you're willing to go through a lot of ceremony, you're a software conservative. If you don't see a point to the ceremony (either because it gets in your way, or you don't believe that the promised benefit is no that big), then you're a software liberal. Which you are likely to be is a combination of a function of your personality, and what kind of software you write.

It really isn't about competence. Competent programmers can fall into either camp. However there is a strong tendency for people to conclude that people who disagree with them are incompetent. As you just did. And then backed up to realize that there are good people who disagree with you.

I would also disagree with your weaker conclusion. In general bad programmers agree with whatever role-model they have most recently imprinted on. If they've picked up a Java book that talks about typing, they assume that it is right and types are worthwhile. If they pick up a PHP book, then vice versa. The current popularity of Javascript and Python mean that a lot are going to be on the dynamic side, but far from all.
