What a bunch of BS...
I love Chabad, stand by them, know three Chabad Rabbis personally....
These Jews do the most of just about any organisation to help the Jewish people do mitzvot and keep Jewish.
I went to Rosh Hashana last week with Chabad, and I am going to Yom Kippur with Chabad tomorrow evening.
There are a lot of people who are jealous of Chabad and I believe that leads a lot of people to hate them. And then there is the issue with perceived Messichism (believing the Rebbe to be moshiach). Out here (in CA) I have not met any Chabad Rabbi who teaches or believes that Rebbe was moshiach. All I have heard is that we are close to the time of Moshiach, and the sparks of Moshiach already exist in the world.
