I said I wouldn't cut off somebody's head if he slapped me. Considering the back-and-forth between settlers and Indians, if it was a case of dealing with people who had massacred family and friends, perhaps I WOULD put their heads on display.
This stuff wasn't limited to the Mormons. And it went back all the way to the early settlements. Putting heads on display was a tradition of Western people going back thousands of years.
Seriously, you're grasping at straws here.
There are so many strawnmen around, it's only natural.
