Their mission is no different than the slow rise of the cultish & dangerous movement of Adolph Hitler.
It took a damned World War to finally reign in the Hate Crimes of that terrorist organization too.
One that targeted a specific part of society, by one insane person or small group, and resulted in the most massive slaughter of humanity.

Terrorist groups like ISIS & Stormfront are mirrors to Adolph Hitler.
Now imagine if Adolph Hitler would have had the Internet available as these groups do today.
