So true (sadly). There was a time (and here I'm showing my age) when progressives said, let's raise all boats, and marched with slogans of unity and solidarity encompassing all. Were poor or middle class white males required to wear sackcloth and ashes and abase themselves as privileged and racist (though some undoubtedly were and are)? No, we sought justice and economic advancement and quality of life for all. But now the pall of identity politics and zero sum game thinking has too often polluted the dialogue. I don't know if polarization can be eroded but we have got to try. The hard right and left zealots are beyond reach, but I see a broad middle ground open to new ideas based not on racial ethnic or religious groupings but on our inherent humanity.
