Yeah, I tend to agree that the WNG trope appeals from the perspective of people overcoming their ordinary -- tastes, really -- to come together in True Love. And I don't think that every use of the trope is as homophobic as some in fandom believe it to be; it depends on how the story is written.
Metafandom had a link to an interesting post positing that as homosexuality becomes more accepted, the WNG idea has less force because "gayness" represents less of an obstacle to overcome. And there are some people who have a "flowers in the attic" incest kink for that reason -- although, as the commenters pointed out, in other instances it doesn't seem to be so much that people actually prefer the incest as it is that in some fandoms, the central "pairing" is a sibling one, and so you're kind of compelled to use incest to get to Teh Sex.
