Salaam,
The Native Americans were robbed and murdered for gold, and silver, and tea, and molasses, and land.
What they could not do in Jerusalem they took revenge in the Americas.
In his book, The Brothers Karmazov, Dosteofsky interjects a conversation between Chirst and the Pope; about the Inquistion. It is worth the read.
I think the Inquistion is alive and well today.
Islam entered the Americas with no malice, no harm, no murder etc.
