So...you're conflating adding the Ten Commandments with removing the names of Confederate generals from schools. Here's an example of two schools that removed their Confederate names four years ago, and are now bringing those names back:

Note that both decisions were made by the local school board. School boards answer more directly to the voters - their meetings are generally open to the public. On the other hand, even if you happen to live near your state capital, it's unlikely you'd be given the opportunity to speak during a meeting of the state legislature. If one school district in Louisiana had mandated that every classroom had to have the Ten Commandments it wouldn't have been national news. But when an entire state makes such a law, people notice. What would happen if a school district in Louisiana refused to enforce the law - something like this?

And you bring up statues, as if to say taking down a statue erases history. It doesn't. History is there to be learned: Take a class. Read a book. We put up statues of people we admire. Nixon was an important historical figure but we don't have too many statues of him.
