In this weeks Parsha - Pinchas, we see that Pinchas killed the evil doers and was thus awarded by G-d with peace! So much for those people that think that peace is attained by sweet empty words. Sometimes you just need to cut them down. The Medrash says that spilling the blood (which could mean killing out right, or shaming - when a persons blood rushes to his face) of the evil doers is like bringing an offering to G-d and brings atonement.
On that note on one of the new Saba blogs nanachtalk.com (I think), the author justifies Sabas bashing of the Rabbi's citing the sources in the halachic book "chofetz chaim" that recommend such speech when it is called for.
Great blessings of Na Nach Nachma Nachman MeUman!
