How does the 14th amendment protect citizens today from discrimination?

"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside. No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."

Explanation:

Everyone who is a citizen of the United States is equal to all other citizens. A law can not be made against any certain religion or race as long as they are citizens of the U. S.
