LB- it’s a known fact that many or most or all Gedolim thought there were some problems with Chassidus at the beginning, although today it is accepted. I could be wrong, but my impression was that It is Time for Truth was not trying to attack Chassidus. The proof is that the source of his comments is the Satmar Rebbe. My impression was that he was just pointing out that there are dangers if it is misused.
But, it is possible that I am judging the post too favorably, and the first sentence could have been phrased better. I’m not sure.
