4. This law was passed to benefit widows

The conflation of two very disparate sections of the U.S. Code is a tip-off that someone is trying the old flim-flam. In 1957, Congress passed Public Law 85-425, increasing the pensions of widows of veterans and for the purposes of defining who was an eligible widow, Congress generously included the surviving widows of Confederate soldiers. The last confirmed confederate soldier died in 1951, six years before the law was passed. The claim is bogus.

As for statues on public lands, I'd prefer we give that space over to statues of Americans who didn't take up arms against our government to maintain their right to buy and sell human beings, break up families, rape women and children, and degrade humanity.
