To be honest, I think Laura Byrne was trying to be funny. But since many people still are under the false belief that Mormons practice polygamy, this kind of joke gets taken seriously by them and bolsters their own false notions:
I believe that Tucker Carlson owes the Romney family, and his supporters a huge apology or risk his online publication becoming the “Infowars” of the internet in short order. Tucker Carlson’s Mormonism does not justify this sort of behavior by his writers. Furthermore, I find it very humorous, that Tucker Carlson would have a woman doing his bidding and insulting the Romney sons, instead of doing it himself. I guess it is true what Don Imus famously said about Tucker Carlson and his bow ties.
