I'm mostly goofing around with this thread, but, to get autistic for a second:
It's hard to say. I haven't followed the developments too closely from some moment onwards, but the opinion I formed is that in the beginning (when he launched MDE and WP) he was definitely just trolling, early South Park style, although there was some palpable resentment towards artsy-fartsy stuff and people associated with it and I think this was the germ of his getting deep into the schizo sections of the online right and he basically "memebrained" himself to death, so to speak, after which point it's basically impossible to tell what he really thinks (many such cases).
I have a rather utilitarian attitude to politics and for me it doesn't really matter what someone's ideological motivations are, only what his/her actions result in - because of the audience he cultivated, functionally he had as much of a malignant influence on the online political discourse as Yarvin, BAP (or, on the left side, the broads from Red Scare or chapofags) etc.
