The radical Mormon sects, to my understanding (which is limited to Under the Banner of Heaven[1]) have somewhat strong textual justifications for their practices: it's a matter of historical fact that the early Mormons were polygamists, were vitriolic racists, &c.
This is in contrast to both reactionary evangelicals (who do not make up all evangelicals) and Hasidic Jews (who are do not make up the entire Orthodox community), where both groups have largely substituted contemporary doctrine (as a conservative religious expression) for historical (and even canonical) interpretations. Compare evangelical interpretations of capitalism (and the "doctrine of wealth") to descriptions of wealth and charity thoughout both the Old and New Testaments. Similarly, Hasidic interpretation to pillars of Jewish doctrine (Pikuach Nefesh, Tikkun Olam).
That's fair, I think you're looking at it from the perspective of similar belief structure and religious doctrine. I was thinking about community size and distance from the "mainstream" beliefs of those religion, not necessarily the way in which they diverge.
