@Drip_Drip it's the job of the SCOTUS to consider such cases.
And it's already pretty common in the US for public dollars to directly fund religious schools, so it's not that this could lead to that. That already happens.
This is more about the opposite, the extent to which states can discriminate AGAINST religious schools by denying them funding they'd otherwise be entitled to.
So this is more about allowing public dollars to be withheld from them.
