American Jews like to say Passover is a holiday about freedom. It isn't, or at least wasn't intended to be. It's main focus is on what a vengeful, bloodthirsty God did for his chosen people. We say it's about freedom to affirm its universal relevance, which is something American Jews desperately want to believe about their religion. All the discussions at Passover about the oppression of non-Jewish groups enable us to ignore the sectarian and chauvinist message of the Haggadah. But make no mistake, the Haggadah is about the elevated status of the ancient Hebrews over other peoples.
The story of Passover is a myth. There is no historical evidence to support it. It's most likely the ancient Jews weren't slaves in Egypt. In all likelihood, they were never even in Egypt. The story was made up for the same reasons any myth is--to cement group identity, score propaganda points against enemies, and offer explanations for what seems mysterious or inexplicable. "We were slaves to Pharaoh in Egypt, and the Lord, our God, took us out from there with a strong hand and with an outstretched arm," we say at the Passover table--best case scenario this is dubious, more likely a lie.
How would Jews feel if Egyptians had a holiday where they blamed Jews for enslaving them, especially when there is no evidence to back up that claim? Even if the Egyptians acknowledged the falsehood of their statements, it would still be profoundly disturbing to know kids across that country were reciting such a profoundly anti-Jewish story. It might be even more disturbing than if the story was true.
Another question: what benefit do we derive from making the foundational myth of American Judaism about persecution at the hands of the Arabs? Jews, of course, have been victims, but the crimes by Europeans against us dwarf any committed by Arabs.
None of this even begins to address the violence of this holiday. We celebrate a God who slaughters en masse. Today we might call killing the firstborn of every family ethnic cleansing or even genocide.
