" There is no obvious comparison between the 2 groups. The KKK never was on the same level of terror that ISIS is"
So the bombing schools and killing children, raping women, actually getting into government seats in the united states and pushing thier murderous agenda, the constant intimidation tactics that prevented peopel from learning. All of this over a period longer than a century. The KKK was a part of the fabric of the government of this country.
Please realize as well that the KKK and its beliefs spawned the many thousands of other White Supermist groups in the USA and abroad.
BE clear that Isis has killed 5,500 in it's reign so far and the entire earth wants to step in. In this country in 2 days from May 31 to June 1, thousands were killed by ordinary citizens who subscribed to those same KKK leanings and teachings but nothing was done. There was no outcry from the world as a whole.
