The Rosh Yehiva Reb Hillel Zaks recalls a story that happened in BMG. An elderly Rov who he does not name here, spoke in BMG in front of RAK and said that Reb Yisroel Salanter said if I would've met the גר"א I would've rebuked him for keeping to himself and not going out to teach the masses and be משפיע on them. Reb Aron got very upset and grasped his shtender with all his might to keep himself from lashing out at the Rov. He later told Rabbi Zaks I would've stopped him if not for his stature and reputation. So were RYS' words not correct? Or was the problem the audience he was repeating the story to? Maybe he didn't believe the story? Well, he explains it in the second paragraph.
