Absolute free speech can have real consequences, here's a sad example from the Rwandan Genocide (copied from Wikipedia):

> The Power groups also believed that the national radio station, Radio Rwanda, had become too liberal and supportive of the opposition; they founded a new radio station, Radio Télévision Libre des Mille Collines (RTLMC), which broadcast racist propaganda, obscene jokes and music, becoming very popular throughout the country.[89] One study finds that approximately 10% of the overall violence during the Rwandan genocide can be attributed to this new radio station.
