I join CC in distaste of the "anti' label...I much prefer "Opposition poster" or "opponents". We are not "anti" mormon (as in all mormons), but opposed to the teachings of mormonism. I guess you COULD say, though, that in the case of the coming election, I AM anti-Romney.
In 1985, Vaughn J. Featherstone, a member of the First Quorum of the Seventy of the LDS Church addressed students at the Church-owned Brigham Young University, calling anti-Mormon material “theological pornography that is damaging to the spirit,”
I know that the LDS church takes a very strong stance against anyone questioning the theology, and Featherstone is not alone in his condemnation.
I'm quite sure you would all scream if we DID start using the "anti Christian" label. Remember there was some trepidation about our even using the neutral "apologist" term.
