4. Philosophy and logic are absent, and are instead replaced by base-instinct universal "wants". For example, they want clean air -- as if anyone else wants dirty air. They want "peace", as if anyone (at least in the western world) wants senseless wars. They want "health care", as though anyone else wants to be sick. Even their "positions" are meaningless: Discrimination against gays was fine when one of theirs (President Clinton) signed the Defense of Marriage Act. And war was fine when he authorized (without Congressional approval) the bombing of a European country (Serbia) that was no threat to the United States -- and when he launched missiles at Iraq. Similarly, their objections to the budget deficit under President Bush vanished when said deficit was to become much larger under President Obama.
5. Their support rests on dependency. They create entitlements (actually, coercive government-enforced claims against others) that leave the "beneficiaries" dependent on oppressive government. The main progressive entitlement is welfare for old people; i.e., Social Security. But after being compelled to make "contributions" to this "fund" for their entire working lives, who would want to vote for dismantling it? Who would, after being compelled to pay for Medicare for year after year, would vote to deny themselves this "benefit" when it becomes their turn to collect? What parent, after paying years of real-estate taxes, would want to abolish "free" government schools and subsidized state colleges? And so progressivism oozes along, growing, and using democracy as a weapon to further itself.
