Again I'm just reading along, and as a person who cares about, you know, the principle of charity, I don't see how you can possibly think that's the most charitable interpretation of what they said.

And here's the crazy thing: I'm not even saying I agree. I just think it's possible to address a face value version of what they're talking about without taking unnecessary cheap shots.
