Here's the full text of the relevant section:

> 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.

The dissents are worthless, like most of the opinions from Thomas and the other conservative "justices". None of this wording is tricky unless you are specifically trying to find ways to deny rights to american citizens based on their ethnic origin.
