 In such writings, this identity goes beyond a formulation of machismo and Lucha libre to something more inherently potentially homophobic, where homosexuality is or was traditionally conceived of as not-Mexican.Alfredo Martínez Expósito writes that though a "conspicuous scarcity of gay characters and themes in Mexican cinema" may be blamed on "a machismo-inflected patriarchy", the image of the homosexual is more likely controlled by "both the image that Mexicans have formed of his own country and the image that Mexico has exported to other countries".Martínez Expósito suggests that "cinematic attempts to introduce gay characters and themes in national cinema should necessarily be doomed" because "Mexicanness" as a concept and identity contains a lot of features associated with patriarchy, which he says explains why Mexican LGBT+ cinema (pre-2001) used various strategies in order to acceptably introduce their themes; characters who are camp but not gay, characters who are closeted, for example, up until "the latent homosexual in "Y tu mamá también"", which he suggests "tested the limits of national tolerance".
