I have to admit that I have no tolerance to neither of these terms, especially the first one you mentioned!

As Satanist and member of the Church of Satan which is the manifestation of Satanism to me, my personal philosophy concerning this particular term is that whenever I hear somebody to use it I correct the misconception and make sure even this one person using the term understands that there is only Satanism, not this or that form of Satanism!
