Analysis:
Iowa goes further than most states by criminalizing not just defacing and mutilating the American flag, but also satirizing and deriding it. Because the main problem seems to be casting "contempt" on the flag, the crime lies in the message being sent rather than the actual act. Even worse is inclusion of "by words" here, which means that using words to ridicule an American flag is as much of a crime as burning it in the public square.
