The Reconquista is Spanish Colonialism Reborn

Maybe somebody can explain to me how Mexican nationalists pushing the Reconquista can be reconciled with the useful idiots’ reflexive spport of “Native American” land claims in the rest of the U.S. territory.  It seems to me that the lands being claimed by the Mexicans are those lost in the Mexican-American War of 1846-48.  These lons will have a lot of trouble wishing away the Indian Territories Map that covers the same geography.
