Since you are new to the FLDS ping list, you might like a little background information on the Principle.
I strongly recommend you visit the Utah Attorney General's web page on polygamy HERE for more information. You should read the AG's Primer on polygamy (there is a link to the pdf document at the bottom of the first paragraph) with the understanding it is emotionally disturbing.
There is an excellent video (approximately 90 minutes long) on polygamy HERE. It is well worth the watch in my opinion. Incidentally, the sponsor provides copies of the DVD without charge to LDS members.
