As I mentioned previously the quote by President McKay which reads that parents need to include in the teaching of their children the "Open and forcible teaching of facts regarding communism as an enemy to God and to individual freedom," has caused my husband and I to reflect deeply. It is not enough for us to simply know and understand communism/socialism but we must know it enough to teach and articulate it to our children. Below I present some information that may help you begin to know more about it that so you may teach those in your stewardship.
Here is a YouTube video contrasting President Benson's message against socialism and President Obama's message today. It is almost 11 minutes long. At least watch from about 7:30 on...
This is also a YouTube video that is part of a talk by President Benson about "The Book of Mormon" and the secret combinations. He correlates how these secret societs exist today in the form of socialism. He references a book to read, "None Dare to Call it a Conspiracy" by Gary Allen. This book is amazing! Here is a link to an on-line copy of the book.
Elder Romney gave a talk called, "Is Socialism the United Order?" He actually gave this talk twice. The first time at BYU (link here) and the second at the April 1966 Conference. Here is a link and here is another link. I highly recommend reading this as this is a very good base to start with.
Elder Oaks gave a talk called, "The Divinely Inspired Constitution" that appeared in Ensign Feb 1992. Here is the the link from lds.org.
