The issue is that "hostility toward" is interpreted differently.
I want to be clear that I am not pretending, and do not intend to pretend, that the Church condones homosexual behavior. Nor do I intend to pretend that the Church ever will condone homosexual behavior, because I think they're doctrinally forbidden from doing so (whereas there was no explicit doctrinal barrier re: priesthood eligibility or plural marriage).
The difference is that Mormons do not consider themselves more hostile toward homosexual behavior than they consider themselves hostile toward other types of sinful behavior, and as detailed above, the leadership goes to lengths to try to ensure that everyone understands that those who practice homosexuality should be treated with the same civility and respect to which anyone else is entitled.
Pro-gay activists, however, interpret "hostility" to mean any disagreement whatsoever with their activities and demands, up to and including disagreement with the demand that these activities enjoy state sponsorship via marital benefits.
We have to accept that there is a basic moral disagreement here. No one is trying to hide that or say it doesn't exist, or imply that it is going to disappear.
The difference is that Mormons are trying to maintain friendly and civil relations despite that, and trying to encourage people to be sympathetic to the homosexual POV without abandoning their moral standards. Meanwhile, the activists on the other side do everything in their power to lay the blame for suicide, death, and many other massive social malignancies on religion, history, culture, politics, and anything else that disagrees with them.
