Yes. And unfortunately, none of this ever is limited to homosexual behavior. These ordinances are usually based upon vague "sexual orientation" language. So, imagine being a business owner or workplace manager. Now sit down & write a long list of various "sexual orientations" -- and all of these so-called "what-they-do-in-the-privacy-of-their-own-homes" can be imposed into very public business. (For example, an exhibitionist could be deemed a "sexual orientation"...as public clothing codes start going by the wayside, good luck trying to pre-empt that "sexual orientation" in your place of work. Every "sexual orientation" under the sun becomes a protected class status)
I agree that this is about more than gay rights but is more about sexuality rights in general. I believe that eventually the agenda will move more towards attacking our right to legislate the age of consent. We already see left-wing activist groups who have no respect for age of consent legislation already. Homosexual activist groups are targeting the schools, Planned Parenthood has been caught multiple times ignoring age of consent legislation as well.
One argument that the left loves to use in regards to gay marriage is “how is hurting you if gays marry?” Of course there are many types of sexual expression that do not directly hurt you but are still morally wrong and dangerous to society. If someone exposes themselves to you in public they are not causing you any direct physical harm. It is only your morality that makes it offensive to you. The left-wing does not accept the morality of a majority as being just cause for legislation though so their agenda will lead to the things you claim if left unchallenged.
This news story is sad because it obvious that the Mormon church does not understand the issue.
