Yes, this is largely true. The one thing it omits is that the Muslims also raided the coasts of Europe for slaves, so that many of the slaves in Muslim countries were white. Probably there were more black slaves, because as the article points out they could be cheaply bought instead of fought for. But Muslim pirates and slavers were rampant in the Mediterranean for hundreds of years, and it was actually the American navy that put an end to the worst of it.

It's highly ironic that politically correct liars in academia have managed to convinced the blacks that Christianity is a "slave religion" and therefore that they should become black Muslims. Islam is the real religion of slavers.

Most of the South wasn't Islamic during the slave era. In fact, there weren't very many Islamic slave-based plantations during and before the Civil War. Other countries have differing experiences (and outside of Europe and the Americas, not much opposition to slavery.)
