I didn't think it was even hidden. Haven't seen anyone here deny it myself. I've seen plenty of our good Northern brothers try like the dickens though. Then one of them will turn around 2-3 days later slip and make a post showing that they did in fact not only own slaves, but had a number of slave markets for the sole purpose of selling them to the people they're ridiculing now.
I live in a city which has scores of monuments to the CSA. If you've got a sharp eye for such things you might pick out which one has been my avatar since I joined this group. Perhaps it is because I see so many of these monuments so frequently that the ahistorical tendencies SOME of them display cause me to disagree with the "monuments" are "history" and can never be changed.
One monument disrespects the confederate dead stating they "Died for States Rights." At the State Cemetary we get some boilerplate about "industrial North" and "agricultural South." The worst offender is the UDC placed plaque inside the Capitol which reads, in part: “We, therefore, pledge ourselves to preserve pure ideals … to study and teach the truths of history (one of the most important of which is that the War Between the States was not a rebellion, nor was its underlying cause to sustain slavery).”
Hiding slavery in regards to the Confederacy is "heritage." History was edited by the PLACEMENT of some of these monuments.
