But the bigger problem is that making "the same God" the trump card argument for interfaith solidarity doesn't exactly inspire much confidence in our ability to respect those religions who unquestionably worship different Gods (Hindus, for example), or those that don't worship God at all (atheists, many Buddhists). I really do wonder what Hindu-Americans think when they hear progressives make this argument as the centerpiece of their calls for religious tolerance. It must be profoundly alienating at best, deeply worrisome at worst.
The better thing to say is that it doesn't matter whether Jews, Christians, Muslims, Buddhists, Hindu, Atheists, or anyone else share a God in common or not. We're all entitled to respect, we're all entitled to be treated equally, and we all should be free to practice (or not) our faiths as we see fit. A constructed sameness of the Abrahamic faiths -- if it even is real -- is worse than unnecessary, it's deeply harmful and exclusionary.
If one does want to make an argument of this sort, I vastly prefer the Talmud's formulation, as articulated by Rabbi Morris N. Kertzer
The Talmud tells us: “The righteous of all nations are worthy of immortality.”* Needless to say, I do not support any forms of retaliation or sanction against persons -- particularly academics -- who do make this argument.
