That's an interesting take. Although I agree that some portion of homophobic, straight men are managing same-sex attraction in a dysfunctional manner (e.g., reaction formation defense mechanism), I think that these cases are the minority. One doesn't have to identify with/be attracted to a group to be prejudiced against them. It would really be unfortunate if the 99% statistic were accurate, as it would mean that a significant portion of homophobia stems from self-hating queer men.
