First of all, that is not how being raised by gay parents works, and you are still not saying what the problem with gay people is. Is it really so bad that they might make more people gay. That is like saying that straight couples should not be allowed together because they might raise a straight child. And aren't you kind of contradicting yourself with that last bit? "The Land of the Free"? That means free for everyone, not just straight people. I'm sorry, but I think you have a very poorly formed argument.

I think that Islam itself is a religion of peace, but the extremists make it seem otherwise

If there was no religion there would be no ISIS, 9/11 deaths, crusades, and much, much more.

If I believed in God then I would say that he is more wicked, being responsible for Hitler and so many others

In my opinion mental illness should be treated just the same as any physical illness. However, it is not. Many people who believe in euthanasia are against suicide. Why? Mental illness can not always be curable. Would you prefer for someone to suffer unimaginable pain for the rest of their lives and still be expected to pretend everything is alright? I think it is more selfish to keep someone alive and in pain just because you want them than it is to choose what feels right for you. And some people kill themselves because they think no one loves them, they are just a burden on society, and getting themselves out of the way is better for everyone. Even though this isn't true, the person is trying to be the opposite of selfish. I'm sorry to all the people that probably offended :)

If a loved one of yours is suffering, why would you allow them to continue living in unimaginable pain when there is another option? If someone is resorting to euthanasia they probably have tried, and either there is no cure, or it could come after many years of agony. Referring to your point about using organs: why is it wrong to use organs from a person who doesn't want to live anymore for someone who does want to, but may not be able to if they don't get new parts?

I think the person should be able to choose if they want to be killed or spend a life in prison in serious cases

I believe that the person should be able to choose if they want to be killed or spend their entire life in prison
