Appears too much like left over Halloween decorations than an altar for prime time television.
Are you meaning the altar in the video? (showed at 2:40 mins - shot at the TV studio). I have seen the ritual items first hand and they are not of poor quality. It would certainly have looked more powerful with a real human skull instead of a stone one, but the real one I have access to could not be used at the time.
The news reporter mentioned a count of 2500 Satanists down under. This seems like an under estimation for a population of over 20 million. What do you think?
I have not met so many other CoS Satanists (though there's likely many who keep to themselves) and I myself am not open about my religion to others. The "2500" number is probably from a census, so it would include all the 'types' of Satanists (inc devil worshipers). I personally left my religion blank on the census, for privacy! So I doubt the census number is accurate when we're talking about a religion that many may be secretive about.
