rational: Well said.
The Vilna Gaon was a Litvak who learned Torah before R. Chaim Brisker, and before the Beis Halevi too. And he was able to become a גדול שבגדולים without them somehow. Can you imagine that?
Was Rav Moshe Feinstein a Brisker? Was Rav Henkin a Brisker?
Brisk is a city, not מדינת ליטא overall. The whole idea that some people have that every Litvak is or must be some type of Brisker clone is absurd and offensive.
