Well I wouldn't say the shooter in Dallas (his name was Micah Xavier Johnson, btw) was a "terrorist". That is debatable. But in any case, what has he to do with BLM? Johnson himself insisted that he carried no ties to any group and acted alone. If I took a good look at a Trump rally of hundreds and saw a few of the attendees were hc White supremacists, could I deduce that everyone there was the same? Can I assume that all White men b/t ages 15 - 45 who're right-wing and own assault weapons are deadly terrorist psychopaths, just because of a steady string of high-profiles massacres throughout the country, one after another?
