That's a troll example, designed to be maximally unreadable. The first four words refer to the class, and the last four refer to the function; moreover, one of the words in the former is implied by the latter. So, when you munge it all together, and include more words than necessary, then yeah, it sounds complicated. Thing is, nobody actually does that, unless they're writing articles that bash C++. (In this case, you'd say that you have a protected base class, whose destructor is pure virtual and private. The fact that the base class is declared "virtual" is of no consequence to the destructor.)

There's no doubt that C++ is a complicated language, but if you're going to criticize it, at least reach for something that's a bit more insightful than "you can obfuscate your code!"
