I suspect you said it all just about there. Some will criticise the content, others the context. Rather than actually contribute in a constructive way, some would rather criticise the way the argument is portrayed, the methods used, the angle taken. With little in the way of a positive contribution either for or against the argument itself, it must be assumed that they have no opinion on [or even interest in] the subject being discussed.
