Well, if the Mormons can baptize the dead, I guess the Satanists can gay-marry the dead.
Satanists Claim They Held 'Pink Mass' That Made Westboro Founder's Mom Gay In Afterlife (The Huffington Post)
"Upon completion of the pink mass ceremony, Catherine Johnston is now gay in the afterlife," notes the Satanic Temple website, which has the cheeky URL www.westboro-baptist.com. "Fred Phelps is obligated to believe that his mother is now gay ... [and] if beliefs are inviolable rights, nobody has the right to challenge our right to believe that Fred Phelps believes that his mother is now gay."
...
The Pink Mass was performed twice -- once with two gay men, and once with two lesbians -- in an affirmation of the Satanist Temple's belief in "freedom and the pursuit of happiness for all people." The temple is now encouraging same-sex couples to visit the grave and perform their own pink masses.

Vice reports that the idea for the pink mass came about in April, after the WBC threatened to protest the funerals of the Boston Marathon bombing victims. The website compared the the pink mass to "the Mormon practice of baptizing the dead, only much gayer."
