I did mention the title of the web page, which should bring it up right up on Google. I can’t copy and paste from my phone so that makes links very hard to get right. From what I’ve seen on this thread’s comments, and even more, from looking into things myself, including more this morning, it seems clear that Catholics were significantly involved in the African slave trade. It would take more research to clear up what can cleared up about specific numbers and parties, like as you mentioned, in Jamaica, but significant Catholic involvement is established. Yet, this article claims to be about “The Catholic Church and slavery,” yet doesn’t address Latin American slavery by Catholics except in passing a few times, and the omission distorts the many conclusions it tries to make while also whitewashing history.
The Catholic Church historically opposed slavery. Some Catholics didn’t.
