Derivative of internet troll; an individual, typically with religious conservative viewpoints, who uses their religious views (their stated morals) as a basis of opposition to incite emotional responses from proponents of certain issues, such as same-sex marriage, assisted dying, abortion and feminism.
That person railing against same-sex marriage on the basis of his religion is such a morality troll.
