He's a pretty outspoken socdem, though he's much more outspoken as a pedo so it's easy to miss. There have been one or two politically-oriented anime where his entire criticism of them was basically being mad at them for being centrist liberals. I think they were garbage isekai, mainly.
It's a little surprising to see him comment on this, but this is exactly what he'd be expected to say if he did comment on it.
