What those people did at Mtn Meadows Massacre was such an unspeakable horror that it will be a stain on people who profess LDS Christianity forever.
If there was a pattern or repeat of this horrendous-massacre then you may have a point; however, since there never has been .... the only way to describe it is that those people who committed this offense were in desperation to ward off what they believed as their probable destruction at the hands of the US Army.
The Massacre happened when the US Army was only 200 miles away from Utah!
Are you such a religiously bigoted jug-head that you actually can’t see a connection? If you can’t be that honest, the spirit of truth and Christ himself cannot be a resident in your heart.
I think The Hawn’s Mill Massacre would be cheered here.
