newhere – You said it perfectly. He is just a regular “harry” from the neighborhood. I challenge anyone to meet him in shul, and ask him to explain any sugya in shas. Better yet, ask him any sugya in Tur Shulchan aruch with some geshmak bais yosef.
How about ask him to explain you a few rambans on any parsha in the chumash.
PUUUULLLLEEEEZE. This guy is a fraud taking advantage of the destitute and unfortunate – including his gabbai, who is being taken for such a ride, it’s nebach not even funny.
None of this is lashon hara, and people should be aware of this fraud.
