However, the absolute apex of Satanic profanity is the Black Mass. That should tell you something.
Believe me...I don't feel "left out". If their exploits tell me anything it's that they hate everything that can be tied to God in a positive way - be it Judaism OR Christianity. They pick out distinctly Catholic things because of the historical presence of the Roman Catholic Church and its dominance of the Christian experience. The key is to NOT allow them to outrage, offend or send us on a rampage - the very thing they WANT to happen. Having a "Black Mass" is not something that is new to those who seek to worship Satan. That they do so is not to say that they are affirming Catholicism - just trying to get the biggest bang for their intentionally pagan buck.
Even back in the times of the Old Testament Jewish patriarchs, Satan worshipers operated and copied many of the rituals God ordained to His people. One example was the offering of the "first fruits" to God. A Jewish man would dedicate his firstborn son to the Lord. But to the pagan gods such as Baal, Moloch, Ashteroth and others (demons, in reality), adherents would actually sacrifice their firstborn children upon their altars of fire or by the sword, putting to death their children to offer to their gods. Satan has ALWAYS tried to counterfeit what God has ordained as good and his M.O. is to place himself above God in all things.
I truly pity Satanists because they mistakenly think, "I'm going to hell anyway, might as well get in good with the guy in charge down there." They don't realize that they have swallowed a lie, because the Devil hates mankind and he will be the one worst punished in hell - far from in charge.
The reason I think that many people who follow Satan probably came from a Catholic background is because they do not understand anything about the grace and love of God and only see Him as hard, cruel, vengeful and harsh. They don't know that going to heaven is based upon faith in Jesus Christ and His righteousness rather than in their own righteousness and having to earn or deserve to go to heaven. They think they are going to hell anyway because they are "bad" and can't ever "get right with God" - but they have been misled and don't know that God loves them and wants them to be saved and to come to the knowledge of the truth. They need our prayers, our genuine care and to hear the true gospel of the grace of God - not our sneers, hatred or scorn. We need to see each individual as God sees them and to never give up on anyone. Always we should hate the sin but love the sinner.
