I don't know why you are getting downvoted. While I might agree or disagree with the argument, it is a clear, politely expressed view.
It is sad HN is sliding in the direction of folks being downvoted for opinions instead of the tone they use to express them :(
I agree with you, but:
> I think it's ok to use the up and down arrows to express agreement. Obviously the uparrows aren't only for applauding politeness, so it seems reasonable that the downarrows aren't only for booing rudeness.
