I don't know about the history & literature courses, perhaps they have a point there. But it certainly would be professional malfeasance if the university counted a creationist biology course towards admission. This is true whether the applicant learned their bogus biology in a Christian school, Jewish school, or Muslim school.
Really, how long do you think these people spend on evolution in their biology courses? It's probably two weeks at the VERY most.
It's not like they're taking a course entitled, "Creationist Biology."
Freedom of ideas is OK with me and these students who have been "indoctrinated on creationism" will do just fine at the university. Probably a lot better than some people I went to college with who didn't know much more than the "F" word and flunked out after a year or two. How did they get admitted in the first place?
I can't see this lawsuit going very far. Both sides are clearly posturing. But it will be hard to claim discrimination when the history of admission is 75% and the standards are not designed to impact any particular school. The University has a right to make admission standards, not a court.
It will be interesting to watch, with the activist California courts, though. My guess is that the Calvary kids are out of luck.
I think it's the parents that have made the mistake and now they want the courts to fix it.
