There is no specifically inherent definition for such a personal article as "harm", though your heart is in the right place. Consider that every individual has a perspective on what causes them "harm". You could assert that only physical harm has substance, but oftentimes mental or emotion distresses can evolve into a form of physical harm. Yet, if a nation protected its citizens from the mental or emotional distresses of others there could be no guaranteed freedom of speech. If this freedom of speech is not inherent to society, there is no way to check and balance the governance of the nation without aggression - which requires the inflicting of physical harm.
