Earlier quoted context omitted.
I highly doubt this is true due my deep understanding of Mormon culture and their ethical inclinations. You are spreading second hand gossip and casting an entire religion into disrepute. Please share facts or reliable reporting if you have such.
Your understanding of modern Mormon culture and their modern ethical inclinations does not change history. Any religion such as hinduism with their caste-based discrimination and mormonism with their skin-color-based discrimination is in their correct place when found in disrepute. Please inform yourself before standing for such shameful and unethical/immoral belief system.
The Mormons could indeed be or have engaged in disagreeable acts (I wouldn't know myself, nor do I care), but claiming so while skirting your own duty to be truthful is not okay. "Apparently" and "second hand" don't fly with accusations.
