“black alternative to Christmas”
That pretty much sums it up.
Let’s not mix things up. There are a lot of devout, black Christians to whom Christmas is meaningful.
My understanding is that this is a “holy day” for non-Christian black people who feel that they need something to set them apart.
I don’t know if the majority or all of the people who subscribe to Kwanzaa are racist, but the guy who “founded” it was a racist, a misogynist, a sadist, and a felon to boot. Nice role model.
