Opinion of the term "regressive left?"

[RaphaelDLG]

Harris and Rubin use it as a lazy ad hominem against those who disagree with their neocon positions, hypocritical pro-Israel stance, and absurd belief that Muslims are uniformly inherently dangerous/ticking time bombs because of their religious beliefs (but somehow Jews and Christians are not also uniformly dangerous - they fail to understand the intersection of religious beliefs, culture, and politics).

There is an element of the left wing that sometimes equivocates and is culturally relativistic in inappropriate ways.  But hated term.
