Could be - there is certainly a long history of millennial movements in the US, and they tend to be the ones who produce extreme fanatics.

Possible. I suspect that both the Expulsion from Spain and the 16th century millennial movements in Eastern Europe (e.g. Sabbatai Sevi) could play a part in it.

I would agree that it did so for the concept of unilinear evolution (e.g. progress towards perfection; sort of the secular eschatology developed by Social Darwinists and others). For Christianity itself? I don't know about that, although maybe for Christianity in Europe.

I suspect that the process goes back to a combination of Hoffer's observations on True Believers and to having a geographical locus for a religious group and seeing that religion being used as an excuse to smash the geographic locus. Just a guess, but it might be worth following up.
