"Here we have a shooter with a clear political motivation, he hates Planned Parenthood, and possibly President Obama. His politics led him to kill three people, which by definition would constitute as terrorism. Despite the facts, America seems to hesitate in calling an act like this “terrorism.” There are other examples as well. Anybody remember Dylan Roof? He walked into a black church and shot nine people dead. He did so because his politics was dominated by his hatred of Black Americans. By every account, what Roof did was an act of terrorism, but wasn’t called a terrorist. What about the Sikh Temple shooter in 2012? He killed Sikhs because he thought they were Muslim and inferior to him. Again, not called a terrorist."
