The third and most extreme category of oppression is violence. According to the Merriam Webster's dictionary, violence is "the use of physical force so as to injure, abuse, damage, or destroy". Acts of religious violence which are committed against people who practice a particular religion are classified as hate crimes. Since September 11th, 2001 the number of hate crimes which have been committed against Muslims in the United States has greatly increased. One such incident occurred on August 5, 2017 when three men bombed a Mosque because they felt that Muslims "'push their beliefs on everyone else'". Acts of religious violence are also committed against practitioners of other religions in addition to Islam.
