I don’t know what point you are trying to make.
You wrote, "Apparently a long time friend of Ravi's doesn't think Ravi's actions had anything to do with Clementi's homosexuality. Unlike a number of posters who concluded that without any evidence at all." Then you quoted the friend's statement as evidence to support your idea.
I'm just saying that someone who's committed enough to the idea that The Homosexuality is the reason can come up with ways of discounting the statement.
My gut feeling, for what it's worth, is that Ravi's friend is at least partially right and Ravi probably would've posted it if what he recorded had any semblance of sexuality, no matter how it was directed.
And the whole affair made the news (and Drudge, and FR) because of the suicide. If it were a suicide after a heterosexual experience, it would've made the news. If nothing as big as a suicide had happened (examples of "big": Tyler shoots Ravi and goes on trial, or Tyler files a high-profile lawsuit and goes for interviews on national TV, or...), probably no one would've posted about it.
None of what I'm saying makes the homosexuality part utterly irrelevant, but it's also probably less important than people who make it a central issue are justified in doing. (I include those who'd use this incident as evidence of Scary Endemic Homophobia, grounds for "hate crime" charges, and ammunition for mandatory "diversity training.")
