> It's very interesting that people form such a personal bond with programming languages, to the point where they will refuse to see how they could be perceived as bad, or cumbersome.

From what I've seen and personally experienced, this happens most often when someone is only strong in that one language. If you've only ever used that language to build applications and someone comes along telling you it sucks, it feels like a personal attack because it would mean you've been doing things wrong or your code/applications suck. It's part of an identity. As people learn new languages and actually gain professional experience with them, that original language is no longer what defines them as a programmer so they no longer need to defend its legitimacy.
