I'm leaning towards yes, because despite their inclusivity and the general feel-good vibes of the stories, the characters themselves flirt with police brutality quite a bit, and who knows exactly what they get up to in their lives outside the novels.
Any more nuanced views from my fellow hexbearians (and lemmings)? I'm slightly less articulate than Detritus on a hot day, and I wonder how much the politics and views of Terry Pratchett comes up in leftist discourse.
