"What are the arguments against them, then?"

The arguments, at least as I understand them, are that they represent a Dip worldview w/o any other views being allowed. And of course there exists neither a theistic nor a Dip monoculture, there is a spectrum of opinions on both sides of the fence.

Adopting a Dip standard of public expression as default is de facto endorsement of that world view. That's the problem and one that I hope will be engaged by this silly court decision.

The problem with that argument is that, if you allow all viewpoints in public schools, then you also keep the door open for everyone else. Not only religious and atheist teachings, but also abortion, homosexuality, and so on. I don't know about you, but I just want reading, writing, and arithmetic taught in public schools, not someone else's political or religious agenda.
