On what do you base that statement? In my experience, many people make a pretty sharp distinction between Hispanic (being about the linguistic aspect of culture) vs Latin (being about the geographic aspect - from "Latin America"). For example, contrast Spain vs. Brazil. Treating the two as synonyms is as fraught as "Latinx" is.
