OK, fast forward and Obama is no longer president. Whoever that president is, they call things like this out as Islamic Terrorism. How does labeling it help do anything about it other than make many Americans potentially turn against all Muslims living amongst us? Remember, in theory, the new President is supposed to be bound to uphold the Constitution, so what are they supposed to do?
Labeling them makes the rest of the Muslim community own up to their problem. Their ego makes it unlikely they would accept condemnation from outside the Islamic community. As long as we refuse to call it Islamic terrorism, we play into their goals because we enable them to have free movement and access to everything in the United States that makes it easier for them to carry out attacks.
If we had never confronted people with the KKK, if we had called them "dissenters" or "workplace violence", would the Klan have ever stopped murdering people and blowing things up?
I regret that so many people were forced to stand like cows in a slaughterhouse rather than being afforded an opportunity defend themselves.
