Believe me, I feel for you, but "closeting" isn't limited to gay or bi-identified individuals. Whole lot of people out there who feel too ashamed to address their sexual proclivities — and pathologically separate it from their public life — of all stripes and varieties of orientation. Homophobia is a separate issue as I see it. On the other hand, I do find that media fixation on "outing" people does usually tend to circulate around homophobic biases.
