I agree with you and have no issues with the ACLU except when they mess up some Christmas play simply because little Suzy Whiner is atheist and her activist Daddy doesn't want the play to bring up any mention of religion even when its a cultural issue rather than a religious one.
I think the ACLU often goes too far, but I am no proponent of a strict secular humanist government even though it may be the fairest way.
Its like forcing a business to spend lots of money to build wheelchair bathrooms when there is only one wheelchair person in the old darn town! Sometimes, bending over backwards to appease one minority is ridiculous in the inconveniences it fosters on the rest.
