I'll keep this post short and sweet. If churches, regardless of perspective want to get in the game of politics, then churches need to lose every tax exemption that is currently in place. It is offensive to me to know that many, particularly conservative, church leaders conflate their personal political positions with what they interpret as the word of God, thus suggesting to their congregations that, say, voting Republican is akin to voting the way God would. The whole purpose of the exemption, if I am recalling it correctly, was to protect churches from the whims of the secular and political worlds, as well as to offer somewhat neutral territory.
Besides, we need the tax revenue.
