Preamble:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence* promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
(*yes, the word is misspelled in the original, hand-written version.)
This is tolerance.
First Amendment (Bill of Rights)
Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for redress of grievances.
This helps define tolerance.
Tolerance is a key to the American vision, which is why it is part of the Constitution.
