For one to even ask this question means that there is no sense of self in the asker, as they are trying to define themselves and their beliefs by another's actions.
If you are a christian then you know Jesus never spoke on this topic, but his elder jews did. The same jews that hated Jesus for forgiving and accepting all of life as a glorious platform to evolve.
Later the followers of Jesus turned his freeing message upside down and mixed regulations into the following.
Here is a question for you. Why do you need to judge another's choices in order to be one with God? Did god not lovingly create the all? Would you judge the sun for being too hot?
Each person is god, each of us are pieces of god, so judging another is judging god.
There is a difference in removing one that may be causing harm to others, from society, but we are still incapable of judging them. This is why all the great teaching say, do not judge. It is an impossibility to judge another through our own life experience.
Gays & Lesbians do not have a lifestyle, as if they are alien, they are part of humanity with a life to enjoy, just like you.
It often perplexes me how churches and religions define themselves, by judging others. Dont they understand that without their ideas of sinners, thieves and wrongdoers, they would not be able to define themselves and what they believe! Without someone or something to point their fingers at, they would have no idea of who they are.
In my opinion religions should be thanking all the people they condemn in the name of god, so religions have something to do.
