I cannot find the citation anymore, but I remember reading about an interesting phenomenon related to this. Since I cannot find the source now, please call me out if it is actually wrong, but it seems to make sense and rings true to my personal anecdotal experiences. Basically, the hypothesis is that immigrant families themselves indeed move away from extremism. But their children born in the new country tend to overcorrect and try to "discover the roots" by swinging harder in the opposite (extremism) direction. One generation down from the one that became less extremist, basically. I might be confusing some details given how long ago I had read it (it might be not the children of the immigrant family, but children of their children, for example), but that's the gist, and I saw it happening myself more than once.
