Lol we didn't see that at the Australian international convention 2019, as they made a man made JW barracade to stop the peaceful protesters showing their posters, stopping them and dropping the f bomb and the looks given to the protesters, it was an embarrassment. Shameful honestly. They didn't try that the following day.
I worked with a direct descendent of the Mountain Meadows Massacre. I learned a lot about this tragedy where over 120 men, women, and children lost their lives to Morman treachery. They used the white flag and promise of freedom to lure the people of the wagon train out in the open. Apparently 8 is the age of reason so although younger ones died, most were older. The mormans even took the bloodied clothing from the victims, and 13 young children. The families of these ones had to fight for a year to get them back. As a side note the wagon train led by Baker and Fancher was extremely wealthy. Fine livestock and horses, one of which was worth close to $1 million, money, furniture, goods,etc was taken; it was never returned. These ones on the wagon train were going to California to start a cattle and horse empire with the animals they had with them. Among the direct decendents and others the belief is strong that Brigham Young was the one who instigated the slaughter. But the LDS church denies that and has not apologised for what they did. There is a Mountain Meadows monument where some of the dead have been interred. The LDS and the defendants have worked to have this done, although the defendants had to push hard for these innocent souls to be recognized. The descendents also fought for and received national park status.
