How so "wrong"? Brown wasn't the only school that slave labor helped build. That was true of UVA and UNC. I can't say for certain that that was true of of the College of William and Mary as well, but it was certainly possible, maybe even likely.
We don't have all the evidence yet. Skilled workers were brought over from England to work on the early buildings. But among the contractors for labor there were slaveowners. It wouldn't be any surprise if their slaves did some work on the Wren Building, as was common practice at the time.
There is nothing more to be said.
I've certainly gotten tired of this nonsense. This is all a lot of trouble over your retarded quiz. But still, you haven't addressed the evidence about the University of Virginia and the University of North Carolina.
That essentially summarizes all of your points.
