Well, it certainly isn't a convincing argument that it is the best of all possible languages, but it does lend weight to it being worth a look in its current form. Personally, compared to other languages I've been forced to think in (Java, C, C++, ObjC, Ruby), it comes out favourably, but I'm quite happy to accept that some people might think it is stupid, dangerously simple etc, etc. and listen to their reasons why - there's room for more than one language in the world.
I hear that a lot. That's not really an argument. People also enjoy stupid things, including things that hurt them, like drugs.
