There is a great desire to see this kind of turnabout - for a long time people have said, without evidence, that the most anti-gay people are closeted, self-hating gay people themselves.
The real reason for this is because that juxtaposition, when it does occasionally happen, sticks in the mind precisely because it's so weird. But good luck backing it up, especially to the degree people portray it, as you have done. (which is fairly black and white, "more hetero people don't really think about this kind of thing")
