The court system is a legitimate way of addressing situations where the majority imposes their will on minorities. I don't subscribe to this notion of saying that it's wrong to ask the "umpire" to make a ruling.
The unfortunate problem here is that same-sex couples and assisted suicide affect you exactly as much as you going to church affects me. These are choices made by consenting adults that do not represent crimes against anybody.
In the case of your state voting for assisted suicide, this is where people are removing constraints that the state imposes. It takes a very long time for people to get to that point on a controversial subject - which is why you guys want to remove the judicial remedies.
All of the complaints you have against a gay couple moving next door to you are the same ones you would have about a black couple, a muslim couple, an atheist on a motorcycle, or anybody else that would add diversity to your street.
Live and let live.
By the way, your point about gays already having rights is not true. I've known gays, for example, that lived for decades with their partners only to find they had no rights whatsoever, after the partner's death, and lost their apartment lease, for example, as a result of not having legal standing.
