So you don't know if other groups are breaking the rules or not, you're just assuming they must be?
Actually, based on the way things are going in this country, I'm predicting what would happen in the scenario I presented. Whether or not it would happen that way, I have no idea. I have a feeling we would never know, because the vehement liberal/progressive community is so vitriolic that they've cowed outsiders into compliance. Basically, the bully mentality forcing people into doing what the bullies want.
While it isn't related to this case or even schools in general, I can provide one example of the kind of racially-skewed bully mentality I'm talking about. Members of the New Black Panther Party intimidated voters in Philadelphia in 2008, singling out white voters and black people traveling with white people and keeping them away from the voting booths. Clearly racially-based voter intimidation...
but the Justice Department decided to let the case drop, rather than prosecute the offenders. You can bet that if the group doing the intimidation had been the KKK, the Justice Department wouldn't have been so quick to let it slide (and I would agree that the perpetrators should be locked up for this!).
So, back to the case at hand... another hypothetical example, if a Muslim student group refused to let a Jewish woman lead their student organization, I would think there wouldn't be one word in the media. But for some reason, Christians - especially white Christians - are perfectly acceptable targets to pick on.
Interesting... while looking for other examples, I came across
this article from 2010 that discusses the same thing, also out of California, with a case going to the Supreme Court. So this certainly isn't a new issue. I wonder how this case turned out? I may have to do some more digging!
