Heather Cox Richardson is a favorite among some of my leftist friends. Her position as an academic offers imprimatur for her wanton partisanship and her acumen as a historical researcher helps her find the cherry-picked details she needs to cover a false narrative with a veneer of historicity. I don't usually engage because her posts are long enough that it would take too much unpacking to deal with, but I wanted to take a crack at just a part of this one. Keep in mind that her schtick consist mostly of framing modern Republicans as morally corrupt and modern Democrats as knights in shining armor for all that is good and right, by peppering her argument with so much actual historical facts that you have the feeling of "context" so you don't notice the logical sleight of hand by which her narrative escapes reason and reality. With that said, here's my summary, responding in snarky kind to her own partisan framing, but faithful to the content of her...
Candid evaluation of assumptions as well as musings on consequences of political, religious, moral, scientific, linguistic and literary truths and pretensions thereto. Dissecting representations, critiquing arguments, discussing liberty, equality, justice, faith, values, facts, and the principles and institutions that make them all possible.
