49 dead dozens injured in New Zealand. Wrenching for a country that was "one of the safest in the world". Where do we go from here?

4 are in custody. i don't know if they all were shooters. But men women and children were murdered. Apparently size age gender didn't matter. It was the color/religion that had to be exterminated. Nowhere to run. Nowhere to hide. Right-wing extremism is taking over the world. Maybe it's time to find other worlds for tthose  who are not white and leave this one to whites only.
