I still don't see it's making a real (rather than symbolic) difference. If you don't have a "recognized" diploma, you can get a GED. And employers and colleges will know who's a worthwhile candidate in spite of the obfuscation.
They might not get to that, but if not it would simply be an oversight on their part. It would be pretty stupid for them to expend all this effort and leave an alternative path so open (course if they weren't stupid, they wouldn't be liberals). It wouldn't be hard for them to make completion of a gay-indoctrination "seminar" (what a yucky word, in this context) a prerequisite for taking the GED.
