One difference between a Democrat and a Republican is that when a Republican criticizes his party, he uses the pronoun ‘we’.
No one should use we when referring to a political organization unless that person is in a leadership role in that organization. Liberals and Progressives should not buy into GOPer group think. That group think leads to a political party where people like Grover Norquist have to pretend that have something in common with James Dobson. Liberals and Progressives should not duplicate that mistake.
Progressives should be willing to support good ideas from any source. Progressives should reject partisanship and instead, remain loyal to the truth rather than a political party.
