Conflict is often used to propel the plot in a story and make things more interesting.
There are no rights listed in the preamble. There is, however, a list of objectives, which is what you probably meant. Here is the 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 defense, 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."
If I'm correct in assuming what you meant, the bolded the section is what you are looking for.
