You're right. While I agree with them on the musical being blasphemous, it does sound as if they have a history of complaining.
I do have to wonder if it is homosexual priests putting on the musical.
Well, if this is the kind of things going on at this "Christian" school then I'd be complaining as well.
Funny, they want parents involved untill the point that you disagree with whatever the administration does.
But your right, no one likes a whiney parent.....
And they like them less when they're right.
That is something that will be in the mind of many people for some time to come whenever they think about Roman Catholic Church activities.
