"According to our analysis: A majority of hateful tweets are coming from smaller towns and more rural areas. For example, some of the biggest spots for homophobic tweets are along the border of Oklahoma and Texas, and one of the biggest hubs of racist tweets is in a seemingly empty area of western Indiana. There are a lot more racist tweets coming out of an area in the middle of North Dakota than in the larger city of Fargo, for example. Homophobic tweets have a wider spread across the nation than racist ones, which are coming from the southeastern portion of the country more than anywhere else."
