the argument is about things that are weird, any effect in a language that means you have to stop and think over scoping rules to figure out why it should be that way is obviously "weird" to my understanding of this word.

In short I'm not sure that they have misunderstood the scoping, they have probably understood it fine, they have remarked on the weirdness that different aspects of JavaScript enables.

Certainly with perfect understanding and knowledge of a language that you do not have to think about at all because it is so perfectly remembered nothing would ever be weird, it is the incidental behaviors of the language at time where you have to stop and think hey why is that, oh yeah, scoping rules and timeout in the call stack, damn!
