Nonetheless, Breivik, unless I'm wrong about it, was not part of a movement trying to dominate the world and install a Christian kingdom, so ISIS differs from the white "movement" in that regard.
In regards to the current discussion, I am not sure which side of the argument I am on. I am not a Muslim so I can only comment from what I see from the outside. I have Muslim friends who are not at all sympathetic to ISIS or any of its friends, so I don't find it hard to believe that most Muslims find ISIS reprehensible as most Christians found Breivik. However, I have the opinion that nations in the region need to step up because ISIS threatens their freedom. There needs desperately to be a fight against ISIS in the form of a fight against their ideology... a movement that teaches that hatred and intolerance is not the way of Islam. I am not a Muslim, so I have no right to demand that of my Muslim brothers and sisters, especially as they've endured much in terms of discrimination in France (as that fascinating New Yorker pointed out) and elsewhere, but the ideology of hatred will survive bombs and invasions, if not be inflamed by it. The only way we can defeat ISIS is to defeat their message.
The biggest difference is - for want of a better word and I'm really sorry about using that term in the current context - because of their ability to execute. They would if they could, they just can't.
And in this simplistic scenario, why would you posit is the reason they "can't"?
I wonder if this is really true though. Some statistics:

While Anders Breivik was shooting kids on the island in Norway, the Norwegian media were speculating that it was most likely perpetrated by muslim extremists. Even though we've historically had way more examples of terrorism perpetrated against immigration related targets by right-wing Norwegians (which was the case with Breivik as well).
The average Norwegian won't remember any of the mosques, immigrant reception centers and immigrant stores that were bombed in Norway in the past. I guess terrorism is quickly forgotten when it isn't your own group that is targeted.
