Wikipedia has a great summary of all the shitos on Lubavitch, ayein sham. You are sure to find one by a gadol you like.
The purpose of this thread is like any other here in the CR- allow people to spew their thoughts and feel like they accomplished something, thereby creating sticky content, causing people to click on ad links, thereby generating income for the website owner. The more controversial, the stickier the content. And thus the sausage is made. Sorry for breaking the 4th wall again.
