Tolerance of sexual diversity in certain indigenous cultures is widespread , especially among Isthmus Zapotecs and Yucatán Mayas . As the influence of foreign and domestic cultures ( especially from more cosmopolitan areas like Mexico City ) grows throughout Mexico , attitudes are changing . This is most marked in the largest metropolitan areas , such as Guadalajara , Monterrey , and Tijuana , where education and access to foreigners and foreign news media are greatest . Change is slower in the hinterlands , however , and even in large cities discomfort with change often leads to backlashes . Since the early 1970s , influenced by the United States gay liberation movement and the 1968 Tlatelolco massacre , a substantial number of LGBT organizations have emerged . Visible and well-attended LGBT marches and pride parades have occurred in Mexico City since 1979 and in Guadalajara since 1996
