I never said it was racist. I said if the movie was made today that the line wouldn't have been included, because these days it doesn't matter if something is racist -- if soemone might perceive it to be, that alone makes it not worth the risk. That is a window into the world we live in at this point in time.
My point was not to pass judgement on what is or isn't racist, or what is or isn't appropriate, or what lines should or should not be in a movie. Only that the lines that ARE in movies, and/or the events that happen in movies, reflect the time in which they are made. Which is why it is so important that a version of the movie exists in which Han shoots first.
