"Homophobic violence...and homophobia in general might also be ways of adjudicating the anxiety aroused in heterosexual men by their own penetrability. If a potential for passive anal pleasure is denied, its denial can be acted out as violence against or contempt for, those who are interpreted as wishing to either experience such pleasure themselves, or to 'impose' it on another. In this sense the repression or elision of anal eroticism in heterosexual men can be seen to work not only along the lines of the masculine/feminine divide, but also along the homosexual/heterosexual divide."
