Untrue. The reconquista crowd has discussed leaving for decades, and would like the southwestern United States to break away from the rest of the U.S. and become a separate Latin American country. Nobody refers to reconquista hispanics as "neo-confederates".
Rather, the term is specifically applied to people who continue to whine about the lost confederate cause from 1865, like yourself.
“Whine” ?
Should states have the freedom to leave the US?
