qwerty, I know plenty of Chabadnikim who are wonderful people, cared about many others, live ehrliche life, etc. I might disagree with some of them on some issue, but have no disagreements with others. I do know many who are not good and pretty clearly off. It seems to me that there are more of latter ones that are younger, and it is not simply an issue of age, as I remember the good ones being younger ;). So, I do not want to disrespect the good ones by focusing on the bad ones.
It also seems that (1) those who were closer to LR in time are better (that would mean that the Rebbe himself was a good influence), but (2) the movement is not aging well, so they were not able to establish a system that will work for the next generation. So, they risked their lives and their children’s lives to help other Yidden, and there was some risks envolved, something worked out, something did not. Again, the movements who only cared about their own, should not be criticizing.
