The leftist Saul Alynsky dedicated his book for leftists to Lucifer. That is who I think most of the left worships. Their actions confirm this.
Look at the attacks on the unborn, the most helpless and innocent of God's creatures. The attacks on the family structure and the moral code that protects us from social destruction. There have even been statues of a satanic sculpture with two young children looking on in rapt attention. Statues cost a lot of money to sculpt so someone has money to support this travesty, also it has been placed in the media so people in the media are being used to put this in the public consciousness. Don't forget that none other than Harvard University was going to have a satanic ceremony but then chickened out.
There have been secret societies going back for centuries, just because most of us don't know about what is going on doesn't mean that these things do not happen. It has been discovered in recent years that the Nazis had a cult which they invented themselves. The Nazi cult was inspired by a book written in the late 18 hundreds. The 18 hundreds was a century that saw the growth of many different occult beliefs. Even Mary Todd Lincoln attended seances to contact the spirits of her dead loved ones.
