Should churches which use their collective political might to deny equal freedoms and rights to all citizens lose their tax-exempt status?

In America each eligible voter gets one vote, one voice. That vote allows them to help determine not only our leadership but also which path should be taken. Churches also have the collective power of their entire congregations and though each member of the church already has a vote and a voice, organized religion regularly oversteps the boundaries provided by their not-for-profit, tax-exempt status and make an illegal transition by becoming political action committees. Should such tax exemptions be taken away when churches knowingly break the rules? Should we be giving them tax-exempt status in the first place?
