United Daughters of the Confederacy (UDC) on Christmas Carols, some are by abolitionists and use to have anti-slavery themes.

I did a lengthy blog on an article in UDC Magazine where the UDC writer explains that some Christmas Carols have abolitionist lyrics and themes.

Somewhat indirectly the author of the UDC Magazine article suggests we shouldn't sing songs written by abolitionists.
