The ACLU for the most part hates and goes after Christianity...so I'd say they are against seperation of Christianity and state..not necessarily church and state..
MANDATING THE KORAN
The ACLU finally finds a religion it can tolerate. Surprise--it's Islam.
When a state university requires students to immerse themselves in the study of a particular religion, it can expect trouble. That's exactly what the University of North Carolina got for its summer reading requirement that all incoming freshmen read portions of the Koran and commentary by a religious scholar. The school now faces a lawsuit from a group of students and alumni, charging violations of the First Amendment.
...The American Civil Liberties Union, normally busy saving the nation's schools from the smallest whiff of religious influence, has leapt to university's defense. Finally, it seems, the ACLU has found a religion it can tolerate.
