Colofornian as well as others have been posting in the religion forum exposing Mormonism since before 2002.
Why is it an issue now for some?
If you and others are annoyed, just don’t get on the religion forum.
Because these are posts not simply exposing Mormonism's false religious beliefs. I would have no problem with that. I agree that Mormonism is a false, heretical, made-up religion.
But these are posts intended for a political purpose: to attack a candidate for political office because of his religious beliefs, when there is no evidence that his religion has interfered in the past or would interfere in the future with his carrying out of the duties of political office.
