Sometimes, when they bark, they don’t bite. But other times, the bark is the prelude to the bite. I don’t think you can judge intentions by the bark, and I am certain you need to always be ready for the bite. Dogs and people are not really that different. Over millennia of history, Jews have been threatened and persecuted–barked at and bitten, and they have not been mutually exclusive.
The Jewish people are few in number and with a small but miraculous and wonderful country–we know that rabid dogs that bark against us, also can bite ferociously, and we must take every threat seriously for our very survival.
