While I do not want to let skyrider use this as an opportunity to continue to avoid the valid question about why homosexuality is a CJCLDS bête noir. . . .
You appear to be unaware of what the Church is doing to reach out to lesbians and gays. Perhaps the following will help to remedy that.

I believe many of us here are aware of the content of these sites, and continuation of the discussion is not thereby ended. It is true enough that according to current Mormon thinking, persons having same sex attraction are accepted (and good on them for that at least), but it is just as true, and clear from these sites, that "homosexual behavior" is utterly forbidden. Insofar as the Mormon church itself or Mormons as individuals act to impose that viewpoint on non Mormons who do not consider homosexual behavior morally unacceptable, this remains a problem. In the case of the church acting as a lobbyist, it is a legal problem. In the case of individuals acting on belief, it is a subject for argument and persuasion. There has been plenty of the former here, but the latter is not in evidence.
It is more a problem in the case of the United States, where homosexual behavior is, in most instances, legally accepted, and where homosexual partnerships are, in most instances, allowed, and where, at least in many places, homosexual child custody and adoption have been sanctioned for a very long time. In this case, the moral argument is focused on marriage itself, and not on the abolition of homosexuality.
I do not want to suggest that dividing inclination from behavior is illegitimate, or persiflage. Many of us have inclinations to do things that are reasonably forbidden, and a large part of morality involves understanding the distinction between what you wish to do and what you really do. However, in this case, the focus is much narrower - any war waged by religious conservatives against gay behavior has long been lost in most areas of civil society.
It seems pertinent to note here that the sources cited (at least the two that worked - the second did not) are specifically related to how Mormons should view homosexual Mormons. Perhaps I did not read far enough, but I did not see much argument here that tells Mormons what to do about non-Mormons. The other thing that seems worth mentioning is that the last of these sites specifically refers to "the sacred institution of marriage." That is a religious term for a religious event. I am not aware of any law anywhere that forbids churches from deciding what they include in, or exclude from, their sacraments, rites, privileges and activities. In states where gay marriage is fully recognized, no church is required to participate against its policy. Civil marriage is not a sacred institution, and arguments about it do not enjoy the immunity that faith traditionally enjoys in its own sphere.
