Loyal, sorry for the misunderstanding – I never said that a people’s status of amalek means that violence is acceptable. It isn’t. The Gaon held that Germans were from amalek way before the Holocaust, yet never advocated violence. Rav chaim’s idea about amalek is that they’re not limited to the physical descendents of the amalaekim, but rather can be spiritual heirs to them.
But to be clear, no one before meir kahanah rationalized violence against anyone on the basis of their amaleki status.
