Many people misunderstand this, I also did till I found out the context. The guy pressing him was playing devil's advocate in order to get a good reaction for the camera. He was very close to Rav Aharon Leib, he founded tens of Kollelim, he's a big personality, and was "raitzing un the matzav"
Spoken like a true child. Thats normal? Play a Gadol Hador for the cameras? Playing devil's advocate is how we end up with piskei halacha in the name of gedolim that were never their intentions. This video if taken out of context can be seen for the and of the following and more:
1. The Rosh Yeshiva called someone a meshugener.
2. The Rosh Yeshiva called a certain yeshiva communist.
3. The Rosh Yeshiva told someone to send kids to the moon.
I mean come on. There is so much wrong with this. It is a good window into seeing how people can drive gedolei yisroel crazy with hypotheticals and "what ifs" to get the result they seek. in this case baby shtick of
"raitzing un the matzav"...
Maybe straighten out those earmuffs and have your hearing checked.
