Which I don't find surprising. I mentioned it because "lame" to describe a person doesn't come up in common discourse nearly so often as "gay" does, so it doesn't surprise me that people are more reluctant to accept it as an insult. It's more common to hear about "disabled people" than "lame people." I don't think I would describe someone as lame unless they did it first, because it seems a little outdated to me. Dickensian. I'd be more likely to say "that child has a limp" than "that child is lame," and I suspect the same is true for many other people. "Lame" as a personal descriptor just doesn't come up that often.
