Baseless hatred. Every Jew with even the smallest Talmud learning knows that this is the reason given in Yoma 9B for the destruction of the temple. Baseless hatred is the reason that we were thrown out of the Holy Land, baseless hatred is the reason that we incurred Divine wrath. To bring blessings upon ourselves and end this curse, we are told that we must rectify this: We must cease from baseless hatred.
Yet have we?
All I ask is that you watch these clips, and think. Really think.
