Now, when we talk of Europeans, we have ample knowledge to point out that the Catholic church was the biggest land owner in france and it was prolifically involved in slave trading.

We also know that slave owners were compensated to the tune of billions and tax payers like me, were saddled with the debt burden from the 1830s.

There's ample knowledge that the royal family made a fortune too.
So your point holds no water; not for a nanosecond.
