No, I don't think you understand. John Tanton established an organization called FAIR (Federation for American Immigration Reform). Tanton is a white supremacist racial eugenicist, and used FAIR to support most anti-immigration political movements in this country.
A tactic FAIR uses is use front groups--groups that purport to support one thing, but really work for the motives of their secret sponsors--in this case, Tanton and his white supremacist homies like Jared Taylor. You can read some about it here.

One front group FAIR uses is PRIF, which purport to be liberal environmentalist group that claims that immigrants are hurting the environment. YVETTE CARNELL IS ON THE BOARD OF PRIF.
Another front group used by FAIR, is Choose Black America, which Jesse Lee Peterson served on. Choose Black America purports to be pro-black and claims illegal immigration is hurting black Americans.
Choose Black America was set up by a white man, who also set up another FAIR front group, this one a latino one called You Don't Speak For Me!
Do you understand now? These front groups don't actually serve the interest they're claiming. They're all about pushing anti-immigration and white supremacist policies. The front groups are used to obscure the motive to their propaganda targets.
So no, they do not support reparations. They support anti-immigration and white supremacist policies. Reparations is just a propaganda tool...a selling point.
