Answer:
There are historical precedents in the United States, and in Texas itself, of people who were denied their civil rights due to their race or religion.
Step-by-step explanation:
More specifically: Texas was a state that allowed slavery until the Civil War, and it was even part of the confederacy.
While the U.S. Constitution guaranteed rights to all citizens, Black people were not citizens, and they were not even considered persons by some states, which meant that their rights could be violated.
For this reason, the Texas Bill of Rights specifies the groups of people who are entitled to those rights.
