This ex-Mormon says going after their tax exemption status is the wrong way about it.
"There is a legal problem here that we realistically need to account for if we are to hold the LDS Church accountable (as well as the Catholics and all those Evangelical churches): The Mormon church did not break any law. It’s within their rights according to the IRS code to advocate publicly and spend money to advocate for political issues. Like all churches/non-profits, they are only barred from campaigning for candidates. The website “Mormons Stole Our Rights” is wrong on the legal facts (it ignores subsection (h) of the tax code they site) and this will lose in any court in America. Ask any tax attorney and they’ll spell it out for you. Even more problematically, the Mormon church itself donated exactly ZERO funds to this campaign anyway and asked its members to donate money; this is also completely within its rights as the law now stands."
