I disagree on the assessment of your picks of the GP's comments, and I'd urge everyone to read through them as well.

None of them is "mean/rude". Perhaps not watered-down to the modern PC norms, but they are perfectly fine and would've not been out of place in an in-person conversation.

You appear to be mistaking expressing an opinion for showing a disrespect or trying to offend someone. That's a slippery slope.
