“Why have a cross? Mormons are not Christians in any way.”
Because the Mountain Meadow Monument is suppose to commemorate the Christian victims of the massacre, not the Mormon perpetrators. That is why the original cairn had a cross on it (which Brigham Young ordered destroyed).
“No sympathy regarding the cross unless they were Christians instead of Mormons.”
That’s the point. The cross is suppose to commemorate the Christian victims, not the Mormon murderers.
I'm sorry, but I was made to understand that the victims were Mormons that Brigham Young had problems with. I don't remember anywhere reading that they were Christians. If that's the case, then they definitely should have a cross erected somewhere.
