I guess this sets a precedent for outlawing any body - related metaphors. For example, saying someone is "broken-hearted" could be upsetting to Meghan Markle's dad, in his current poor cardiac health. "Stiff upper lip" could be construed as taking the proverbial out of people with facial paralysis. Or getting "cold feet" over something could be a reference to circulatory disorders. As for the "long arm of the law" that's obviously a snide reference to those unfortunates suffering from Marfan Syndrome etc.
