You don't know what you're talking about. States are nowhere said in the law to posses "rights". States only have "Powers", and only persons have rights.
Good catch. I used the wrong word.
I used “right” instead of “power”
“It’s a power that was given to the states. Not a right to the people.”
Thomas explains it much better than I do.
Here’s what he says.
the Clause made clear that Congress could not interfere with state establishments
the prevailing view that the Constitution left religion to the States. ... History also supports this understanding: At the founding, at least six States had established religions.
the Establishment Clause is best understood as a federalism provisionit protects state establishments from federal interference but does not protect any individual right. These two features independently make incorporation of the Clause difficult to understand.
Good point, Diamond.
