Of course Google has that right. I question whether it will have the intended effect, though. Pretty sure isolating extremists tends to cause further extremism.
There is a challenge in isolating extremists while not isolating (and, indeed, productively engaging) the communities from which members are radicalized, and quite often brute-force efforts to isolate extremists (especially ones keying on race, nationality, and religion) end up isolating the feeder communities with the extremists, which is about the worst possible outcome.
