The ones I didn't vote for are medical testing on animals, death penalty, fur, and cloning humans.
If humans want to improve our circumstances -- which usually involves worsening them for other species -- then we should have the balls to either take the risk ourselves, or find ways to do it without using a live, sentient creature (which is actually possible now, so there's really no excuse). And if you're curious, yes, I'd be willing to put my money where my mouth is for the right cause.
Death penalty? There is no way to know we have the right person. There is no justification for killing someone when we have other ways of protecting society. And let's remember, that's what the criminal system is for: to protect people.
Fur I wouldn't have a problem with, EXCEPT for the way it's harvested, if someone like me were to buy it. Do I care if some tribesman is wearing fur? Nope. Because I know he took down the animal as quickly as he could, ate all of it that he could, and used all the fur he could, and that he actually needed all of those things. But in the developed world, animals are often skinned alive for their fur, and then just left there to bleed to death. The rest of the animal is simply wasted. That is completely unacceptable.
Cloning humans is a more complex one to explain. First is that clones often have poor health outcomes. The weightiness of simply bringing in life is heavy enough, without bringing in life you know will suffer extraordinarily. In addition, there is no altruistic reason to clone anything. Regardless of their DNA, they will still be a different person than the original. So the only reason to do it is idle scientific curiosity, or an obsessive desire to pretend death doesn't happen. Neither of those things benefit the person who was cloned.
The ones I voted for are stem cell research, gambling, "fornication," assisted suicide, polygamy, and hunting for food.
Using embryos for research is really not complicated to me. Embryos do not feel things or suffer. There is simply no reason not to.
Gambling is perfectly fine in moderation. It's a person's own decision where they want to throw their money.
Sex without a marriage license seems like a completely silly thing to even care about. It's just a piece of paper. It says nothing about the situation, and people should not feel guilty for having sex without a piece of paper.
People have a right to their bodies absolutely, which means they have a right to decide when they die, and if they require assistance and have found someone willing, they have a right to enlist that person's help.
Polygamy is a non-issue unless you're talking about the slavery-type that exists in some cultures. The simple state of having a relationship that involves more than 2 people just isn't anyone else's business, for the same reason fornication isn't.
Hunting for food. I would actually rather hunt than buy from a store. That way I know everything about the animal that I need to know; I know they died as quickly as I could manage. I know all parts of them went to good use. And I know they were free up until that point. I consider all of these to be important ethical considerations, which are very hard to prove with store-bought meat. Unfortunately, I don't really have the situational ability to hunt. But, on the other hand, I don't eat much meat. I don't desire it very much, and when I do, it's usually fish. So it's not too tough for me to seek out fish who were wild caught from managed areas to ensure environmental stability.
