They actually list a number of cases they handled in the second link of my last post. Here it is again for your convenience. Here is just one example from the link:

The ACLU of New Mexico (2005) joined forces with the American Family Association to succeed in freeing a preacher, Shawn Miller, from the Roosevelt County jail, where he was held for 109 days for street preaching. The ACLU became involved at the request of Miller’s wife, Theresa. http://www.stcynic.com/blog/ archives/2005/08/aclu_defends_another_street_pr.php; http://www.aclu.org/religion/gen/19918prs20050804.html

I agree with the christians in this one though, the kid should have been allowed to come dressed as jesus if he wanted. That was just a ridiculous action they took.

From their website:

Religion is pervasive in the public square in the United States - and it is constitutionally protected. The ACLU has long defended individuals, families, and religious communities who wish to manifest their religion in public. (Learn More) Particularly when compared to other industrialized democracies, religion plays a prominent role in American public life. Churches, synagogues, mosques, temples, cathedrals, and Gurdwaras are plainly visible in the public sphere and their right to display religious symbols and to construct religious edifices is protected by the Constitution and by statutes.[3] The ACLU has supported the right of people to preach their religion in public places and to go door-to-door to spread their religious messages. The Constitution properly protects the right of religious figures to preach their messages over the public airwaves. Religious books, magazines, and newspapers are freely published and delivered through the U.S. Postal System. No other industrialized democracy has as much religion in the public square as does the United States.

I truly don’t understand why many religious people believe that the ACLU is somehow against them. Perhaps you can enlighten me, Scott.

Didn’t we already go through this with school prayer? Student-initiated prayer is ok, school staff-initiated is not. This seems like the logical extension of that consensus. It’s a good compromise as well. Neither church-state separation nor freedom of speech is violated.

Shame on the school to make this an issue. It lends credibility to the usually incredible claim that us secularists are trying to ban all religious expression. I can’t believe I’m saying this, but I agree with the lawyer from the Alliance Defense Fund, “They explicitly discriminated against Christianity.” I’d rather have seen the ACLU handle this, though, since I would then know they were doing it for the child’s rights and not for the promotion of Christianity.

“Oh, i’m so insecure, I really wish I had something to believe. Know what? I’m going to take the first religious thing I see as a sign….tralalala….

Wish I didn’t go to one of these sensible schools, this take forev…hold on….Ahh, Christianity it is then”
