Me: Horses can run faster than people!

You: "Faster than people"?! That's a hopelessly vague and unhelpful comparison. No horse can ever go faster than a human if by "human" you mean a human equipped with whatever tools the human may choose to use, because those tools would include the horse against which you would have it compete. So the comparison only makes sense if you restrict the human in some way.

Me: Um..

:-) The other stuff you say makes perfect sense, but that first bit is more pedantic than fair, I think.
