These changing demographics took place well before the 1960s, especially in urbanized environments. It seems people were able to work out on their own what they wanted in their school curricula without judges imposing it on them.
Chaplains provide beneficial spiritual guidance for those who want it, but no one is required to participate in any sort of religious service.
No one suggested requiring schoolchildren to participate in religious activity. That doesn't mean schools are somehow constitutionally obligated to censor their curricula to avoid offending small minorities.
Demographics continued to change and are still changing. When I started school in 1985 there were only white kids in my class, by the time I graduated high school in 1997 a good 15% of my class were minorites. And even when it was all just a bunch of white kids, all of our parents had very different ideas about religion.

The Constitution and Congress mandate equality, judges merely enforce it.

The poster that I originally responded to was indeed suggesting just that. And schools are not required to "censor curricula", just to maintiain neutrality on the subject of religion.
There is quite a large contengent of people out there who keep trying to inject their religious beliefs into public schools. I know that not everyone wants public schools to be avowedly secular, but given the fact that students come from a variety of backgrounds and beliefs it really is the best way to make sure that everyone recieves an equal education.
