Thoughts on white people having to pay slavery reparations?

Why do people think that only black people were used as slaves? Barbary pirates would raid coastal European towns to kidnap white townsfolk for slavery. There's never any talk of seeking reparations for that.

The transatlantic slave trade was made possible by African tribes selling members of other tribes that( they had captured to use as slaves themselves) to the European traders. There's never any talk of reparations from them.

In ancient Egypt, Greece, Rome, China, Gaul, and pretty much any society, the powerful have made slaves of people, no matter their colour. Again, there is never talk of reparations there.

And it's rather depressing that no one ever talks about how the British royal navy was instrumental in ending the transatlantic slave trade, or how the UK spent £20 million in 1833 (40% of national budget) to do so, after making it illegal for any British person to partake in owning or trading slaves in 1807 (yes, it took 26 years to do it, but no government seems to do anything quickly)... and yet never sought reparations for that.
