It has alot to do with this debate, as typically those on the religious right will attempt to group sexual perversion (ie pedophiles, necrophiliacs, beastiality) into the same group as homosexuality. It hasn't been displayed thus far in this thread, but Bond mentioned that it did happen at MAD.
I would be willing to bet that if you were to ask, a majority of the MORGdom would equate the two, and not only that, but that they would also recommend similar "punishments"...and this is my personal opinion before you go all crazy on me.
Finally, I am glad that at least you have the insight to see that the two subjects aren't related.
Homosexuality very much is a sexual perversion, from the point of view of Jedeo/Christian moral and social philosophy, but that does not group it with fetishes or peculiar sexual obsessions such a necrophelia or beastiality. Pedophilia, despite decades of Gay lobby propaganda, is a particularly acute preoccupation in the Gay community (and interestingly, 354 words out of 12,000 in the
Queen's Vernacular are directly related to sexual attraction to or sex with young boys (mostly variations of the "chicken" theme, in one manner or another)
Your claim that most faithful Mormons would recommed casteration, or any legal sanction, unless that person has committed some actual crime, sounds like a paranoid fantasy. At best, its a subsitute for rational engagement with the "religiious right".
As a Libertarian/Conservative myself, I support no "punishments" for private homosexual behavior, but still consider it a sin and, as a mass social phenomena, dangerous, at some point, to the continuation of a free and civil society. But again, that occurs on another level from private behavior as such.
