It’s utterly in character for Lidington to mock him, and heaven knows he’s done far worse, but ugh, I was still pretty irritated on Hunt’s behalf! Though I don’t have personal experience to draw from, I agree with you — it’s refreshing that Hunt’s stutter hasn’t been used for comedy, or as a shallow characterization tool, or any other unpleasant little low-hanging trope. It’s just, like … a thing. He’s just a character who just happens to have a stutter — and a really compelling and well-crafted character, imo!
