For all you snowflakes in academia . . .
Will makes the important point that progressives (including many academic historians) are in a perpetual state of being offended. As Will points out, "those who constantly find reason to take offense are rarely happy people."
This is so true and is something which can be observed as the PC control freaks move from one "offense" to another. For example, first the cry was for no Confederate flags on government grounds, then there was a wink and a nod to the vandalizing of Confederate (and other) monuments as an "expression of art." Now we're seeing some suggest the NPS should not even allow the Confederate battle flag on reenactment battlefields (or graves).
And, as I've pointed out numerous times, the low-hanging fruit of Confederate symbolism are the easy targets to soften up Americans. Those who "constantly find reason to take offense" have their ultimate sights set on the Founders, as we are already seeing.
So keep denying and poo-pooing PC. You're seen as a complicit fool.
