I don't think this argument is valid. Were Zeno and Marcus Aurelius not Philosophers? Chrysippus or the countless others involved with Stoicism weren't philosophers either? Firstly, most philosophers never wrote anything, as the writings of Plato, Aristotle, and most of the other Greeks came from the lecture notes of their students. Secondly, Stoicism may be used to justify not-nice behaviour, but it doesn't mean it still isn't philosophical; it still aims to answer fundamental questions.
