It's really hard to contain the snark in response to this screed. But, this is also a serious question: When you lump large numbers of people, each with their own beliefs, principles, and motivations, into a fictitious group you dub "the Latte Left," isn't shocking how they don't all speak and act in a consistent manner?!
That is, when criticizing and throwing accusations of perfidy, name names and bring receipts. None of this innuendo, and absolutely no passive voice. As far as I can tell, this author isn't talking about any real person.
