Gen 6 is not my interpretation. It says clearly that angels (evil ones) had sex with human women. That's a fact so yes God must have allowed it. He also allowed Sodom and Gomorrah, did he not? He allowed Hitler and Stalin and will allow the False Christ to come and deceive many. just because He allows something doesn't mean He condones it and doesn't mean He won't punish it when He is good and ready as He did to the Earth, to Sodom, to Hitler, etc.
As for this whole topic, keep one thing in mind, Satan worship is often associated with sex, usually bizarre sex, but sex nonetheless. The Freemasons use sexual symbols a lot and they are clearly a cult. Check it out yourself.

Harlotry and Adultery have been symbolic to Satan worship/Idolatry throughout the Bible. The points I made back in #99 stand and nobody has offered a good rebuttal.
But clearly, this topic is too much for some people and in the interest of good Christian harmony, I will stop discussing it with you all. Believe as you wish and I will do the same. Some people can't have an intellectual debate without getting all emotional and resorting to name calling. If that's how this topic causes people to react, it is best to end the debate now.
