At any moment, the ACLU should step up and fight for the American people. Their site prominently states, "The ACLU dares to create a more perfect union — beyond one person, party, or side. Our mission is to realize this promise of the United States Constitution for all and expand the reach of its guarantees."

I'm sure they mean for everyone, right?
