We see a certain amount of activism in the Satanic community (most publicly with The Satanic Temple), so I just thought I’d give my own view on the sort of things I’d find relevant to Satanic philosophy for myself.
First, let me say there is no obligation to support any cause as a Satanist, and no expectation – Satanism is just too individualistic for that. However, here are a few things I can see as compatible with Satanism.
Satanism is very concerned with the individual and with individual sovereignty, so anything that adds to individual freedom and responsibility would go well. Censorship would be anathema to most Satanists where it affects them. Similarly, attempts to infringe upon the bodily autonomy of the individual could easily be opposed from a Satanic point of view. Free speech would be a natural thing for a lot of Satanists to support.
Satanism holds carnality and carnal fulfilment high in its estimation, so the moralistic restriction of sexual and other physical forms of gratification would generally be opposed, as would prying into the private lives of others. The exceptions would be where the will and consent of an individual is directly violated by another, so consensuality comes into play, as this reflects the issue of individual sovereignty. Needless to say, children cannot give adult consent so are not in the equation here.
Satanism holds a particular appreciation of the qualities of children and animals, who to an extent have the properties of natural Satanists (being closer to Nature and instinct), though they can’t themselves be Satanists, as Satanism requires human maturity. So the prevention of abuse of animals and children would be a natural concern for many Satanists.
Nature is also held in high regard by Satanists, who see us as animals most essentially, and part of Nature, so preventing the destruction of natural environments could be a cause that appeals to a Satanist.
As Satanism is a natural opponent of the imposition of religion upon individuals, secularism and religious freedom would be supported by many Satanists, though it needs to be pointed out that “religious freedom” means the freedom to practice any religion you choose, so long as you do not infringe upon the rights of others. It doesn’t mean freedom to infringe upon the rights of others in the name of religious belief. Related to this would be resistance to things like blasphemy laws, and prosecution for obscenity or nakedness.
As Satanism is so concerned with individuality and individual freedom, it makes a natural opponent to collectivising philosophies that seek to define and impose laws upon people according to what they are, rather than who they are, as an agent exhibiting their own behaviours.
And not least, Satanists are natural opponents of the hysterical demonization of people, whether it is the “Satanic Ritual Abuse” craze, or other kinds of scapegoating witch hunts. Satanists might well work to counter these kind of destructive and deranged mob mentalities.
But in everything, a Satanist makes their own ethical and rational enquiries into what they may or may not support or oppose, and takes responsibility for their choices. What should be noted though, is that making others feel like they should take part in supporting any kind of cause through moralism, shame or guilt can well be seen as a unskillful act that elevates emotional manipulation over reason or insight. Similarly, jumping on political or social band wagons can be fraught with the problems of participating in herd mentalities of dubious quality.
