RE: I personally know more Black people who have used those sites than White people.
Can I recall a crude and cruel joke?
Doonesbury had a series of strips as the Roots book and TV movies were at the top in popularity.
At a library, the young black guy’s pal was found to be at a work table between tall stacks of thick volumes of ship boarding list records and histories of countries.
“Would all this be Roots related may I ask?”
“I’m, uh, just doing some research about my background.”
“Well, if you ever track down who your father was, let me know.”
A lot of the problem Black people face in trying to trace heredity is that they were here as slaves a couple of hundred years before any real birth records were kept in the States, and many slaves didn’t have the sort of family records that White families may have kept.
A lot of them are interested in where they and their ancestors may actually have come from.
