"Gaping One-way Hole" in Wall of Church and State infuses religion into government. But That would Mean…

Tea party's and conservatives would love to infuse their religion into government policy, but if government is constitutionally prevented from promoting religion, how is what their doing a not a massive contradiction?
The Las Vegas Sun had this interesting take on this incredibly obvious problem missed by Sharron Angle and others:

Although many Americans view the separation of church and state as one of the keys to the nation’s success as a multicultural society, Sharron Angle believes that religion has an expansive role to play in government. And, she has repeatedly said anyone who opposes that based on the claim of separation of church and state misunderstands the Constitution’s ban on “establishment of religion, or prohibiting the free exercise thereof.”

Angle’s view of religion’s role in government parallels that of a religious political movement — Christian Reconstructionism — seeking to return American civil society to biblical law. Reconstructionists’ primary mission, however, is to “reconstruct” the family, the church and the state according to biblical law.

To accomplish that, Reconstructionists interpret the separation of church and state doctrine as a constitutional wall protecting the church from the state. But unlike most interpretations of that doctrine, the Reconstructionists’ envisions a gaping one-way hole in the wall that allows Christian doctrine to infuse government. In other words, government must not interfere with Christians’ efforts to enact God’s law at home or at church and government itself should be run according to biblical law.

Government by any other name is…Christianity?
