Comlink, the Chassidic movement started as a populist movement that told those who were marginalized because of their ignorance that they could be good Jews even if they were unlearned. Ironically it became highly stratified in a way that the yeshiva world had never been. For all its shortcomings (and it has many), OO, IMHO, is trying also trying to keep marginalized Jews from going completely OTD. However, like the Chassidic movement it needs an opposition to show it where it is going too far. Hopefully it will merit a leader who will realize this.
Abba, I do not have the exact citation right now but I believe that Chazal say that they were slaves from other nations who saw an opportunity to break free. Why should Egyptians who were disillusioned with paganism leave to join another religion and immediately try to undermine it?
