Seeming to be disingenuous

I used to be all caught up in what pyrrhonism was saying until I see people trying to argue for it. It just seems to me that you cannot do that without contradicting yourself. That anything the levy against other philosophies can be done so against their own. Especially in the case of this guy where he seems to use it just to date his grudge against materialism and science/atheism. He doesn’t seem to realize that pyrrhonism extends to ANYTHING.
