Both of these are false. Source: am Mormon The first is not taught in any LDS doctrine. Anecdotal experience of myself and everyone I know shows Latter-day Saints are significantly less likely to believe in Bigfoot than your average person, and the only people I've met who think Bigfoot is Cain learned it from Ancient Aliens and were from any religion. The second is misleading. We believe SOME Native Americans to have SOME Israelite heritage. We also believe in freedom, natural families, gender being an eternal aspect of your identity not based on feelings, self-sufficiency, thinking for yourself, helping out your neighbor, trying to live a virtuous life, and in the literal second coming of Jesus Christ. If you would like to discuss that more, I would be happy to answer questions you have to the best of my ability, but the world and even this site have enough agents of misinformation seeking to divide and destroy every person not a Satanist Jew or their slaves and servantnts.
