Then you disrespect the people of a nation, library people, author, families of soldiers etc. etc.
Real living people that can be hurt by these actions.
Ahh, tree falls in the forest. So if no one is aware of actions that would be considered disrespectful are they still disrespectful? Also if one group considers something a sign of disrespect but no disrespect was intended did disrespect transpire? What if the disrespecter is aware that their actions would be seen as disrespectful but don't consider that view to be legitimate, are they being disrespectful if they do the actions in question?
