First, in order to sacrifice something to someone (or something, I suppose), it has to be dedicated. There has to be a ritual. There are many elements to a ritualistic sacrifice and abortion doesn't fit the bill. Do you actually know anything about Satanism, witchcraft, human sacrifices, or Black Masses? Because I do. I've seen WAY more than I ever wish to talk about. Much of where Christians get their information on all this stuff is from nonsense websites that (surprise, surprise) the enemy uses to create confusion and fear.
And the appeal to the supernatural you've mentioned is to the God we serve. I'm surprised that you even made that statement. Abortion is a travesty, and it breaks my heart. But it isn't ritualistic human sacrifice. Does Satan delight in it? Absolutely! Were the people who were praying to God for more money and the like to continue to kill people wrong? So wrong that I honestly question their salvation. However, it is not outright Satanic worship. If you'd like to talk about real Satanic worship, shoot me a PM. If you'd like to talk to someone who has been involved in things that you think you know about, give me a shout.
