If the Satanist is the ultimate authority in their own life, then so must be their right to do with their body as they please. It was good to read that the power of the churches were enthusiastically broken recently when 62% of voting citizens approved same-sex marriage in a referendum in Ireland.
In probably the only nation on this planet where Catholics and Protestants are still killing each other in the name of their religion, the Irish, manifested their will to break the hold of religion over every aspect of their lives, by opposing the desire of religion to maintain its control over the individual freedom to marry same-sex partners. Because citizens were only allowed to vote in person, people from around the world travelled to Ireland for the sole purpose to cast their vote. The oldest supporter of same-sex marriage was a 101-year-old.
Since marriage is legally only a contract between two people, and can be done in any religion, or in a non-religious civil-ceremony, it made no sense that one religion could be allowed to have sole authority over all other religions and over atheistic individuals over the concept of marriage or over who could marry.
The Republic of Ireland will now change its constitution to join 20 nations around the world were it is legal for same-sex individuals to marry.
