the Leftists are not progressive as they support racial quotas, killing of babies in the womb (a regressive tactic dating to pre-Christian times), Big government (paternalistic oligarchy) instead of individual responsibility
They are NOT "progressive" -- they use that term to label us, their opponents as "non-progressive" or "regressive" whereas that latter label better befits them.
It's like when they collared the term "liberal" -- heck, they aren't liberal economically (less government interference) -- liberalism isn't truly left or right. Or the term "gay" to describe homosexuals, etc. or even the term "abortion" instead of "baby killing"
