How Can TEXAS rewrite history?

In May of this year, the Texas educational board voted and manipulated history, social studies and science. In an effort to enhance the role of "God" and the conservative agenda throughout our country's history and world sciences. One significant change made when rewriting history states is the idea that the founding fathers of our great nation were Christians and indeed, many of our founding fathers were Christians.There were large groups of many religious factions; Mennonites,Amish, Puritans, Jews and in fact several of our Founding Fathers were Deists.
Deism is a religious belief not big in practice today. The core of Deism believes that there is indeed a God who created man, then left man alone making him solely responsible for his own actions on this planet, to act on critical thought and reason. Deism pays no attention to the supernatural or miracles, and believes all things can be explained through reason. Deism reached it's height of popularity during the late 18th century, after the Age of Enlightenment and its ideals and perspectives were entral to the conception of our nation's Constitution and was the religious orientation of such scholars as Thomas Jefferson, James Madison and John Adams. One of the most central and discussed component "the separation of church and state" is a direct result of the Deist influence.
Our country was founded nearly 250 years ago. . . the founding fathers; George Washington, Alexander Hamilton or Thomas Jefferson read many of the same books and studies that high school and college students read today. Authors like DesCartes and Nitsche and were well versed in the sciences such as the discoveries and hypothesis of Isaac Newton. These were men of knowledge and intelligence who were specific in their quest for a superior form of government and intentional with their diction.
Apparently, the Texas Board of Education didn't want to stop with changing what Texas students learn about history, they would like to ban "pro-Islamic" texts from Texas schools, removing books that could be interpreted as anti Christian or pro Islam instead of teaching them about the beliefs and cultures of others.
I find it appalling that we, as a nation who's First Amendment right protects freedom of speech and the freedom of religious practice and beliefs, continually stand by and allow our recorded history to be edited to reflect an inaccurate historical view AND remove books from the hands of students that teaches the belief system of Islam, which in it's true form is a peaceful religion.
Separation of Church and State. Let us not forget that we are a country built on religious freedom which was designed to protect its inhabitants from religious persecution, no matter what one's religious orientation is, whether one is a Deist, an Atheist, a Muslim or a Christian.
