In all your comments you seem to be hitting the nail on the head.

Someone can say the German language is a bad language. But it is not the language that is bad, it is the person's perception.

When they try to evaluate German while thinking in English it is no surprise they consider it sub-standard. Germans, OTOH, are much better equipped to evaluate the German language than those who only know how to think in English.

(Full disclosure; my grandfather was German but I only know how to think in English.)
