The process by which a false masculinity is imposed upon masculine-identified men, a pseudo-masculinity which forces them into the denial of their same-sex feelings and an exclusively "heterosexual" expression of sexuality.
Heterosexualization is most widespread in the industrialized and post-industrialized West -- the US, UK, EU, Canada and Australia;
and is accomplished through the destruction of all-male spaces; the forced mixing of the sexes, particularly in adolescence; and the identifying of masculinity with exclusive "heterosexuality."
In reality, it is both normal and natural for masculine-identified men to have sex with other masculine-identified men.
Under heterosexualization, however, masculine men who acknowledge their same-sex feelings and desires are shunted off into a ghettoized "gay" space which is dominated by effeminized males.
In such a space, masculine-identified men are often accused of being "straight-acting"; and come under immense pressure to assume more effeminate behaviors, including anal penetration and promiscuity.
We should be clear that absent heterosexualization, there would be no "homosexuals."
Nor would there be "heterosexuals."
As one of our Warriors has said,
Male-male sex is isolated only because in the West, its spaces and its customs are completely heterosexualised (i.e. made mixed gender with pressures to be heterosexual). But heterosexual spaces are themselves unnatural --- and it was only through financial and technological power brought by industrialisation that the western society could create such an artificial unnatural heterosexual environment.
Heterosexualization is an historical process which
Crucial to this process is the denigration, curtailment, and dismissal both of the male's natural male aggression; and of his natural male attraction.
Under heterosexualization, the male is steadily divorced from contact with other males, and forced into constant contact with females; while the two key attributes of Natural Masculinity, male aggression and male attraction, are forbidden him.
