Our sexuality is fluid: It cannot be oppressed. Denying our sexuality simply causes its waters to flow into other areas, sometimes in very unhealthy ways, honestly and expression fare much better than repression. Satanism is informed by modern and learned psychological, medical and scientific opinions on sex, there is no dogmatic principles or religious intolerance of sexuality within Satanism. It is very optimistic, positive and healthy: This can only be expected of such a carnal religion of the flesh such as Satanism!
As a result, nearly all the Satanists I know of (and goths, punks and other alternatives) who are also gay are not part of the gay scene and rarely mix with the pubs, clubs and events organized by the popular homosexual communities. Satanists who are homosexual are very much free to be public about it, and the founding members and High Priest of one Satanic denomination are openly gay. Satanism is pro-homosexuality because Satanism is out and out pro-sexuality of any (consenting) kind. To use the vocabulary coined by LaVey, it is these groups search for the Good Guy Badge that leads otherwise promising movements to be imbalanced.
and from the Satantic Bible
"...the Satanist would not intentionally hurt others by violating their sexual rights. If you attempt to impose your sexual desires upon others who do not welcome your advances, you are infringing upon their sexual freedom. ... If all parties involved are mature adults who willingly take full responsibility for their actions and voluntarily engage in a given form of sexual expression - even if it is generally considered taboo - then there is no reason for them to suppress their sexual inclination."
Anton LaVey's The Satanic Bible pp70
