Everything manifests from God. Atleast that is what my religion teaches. I'm a Hindu. Hell and Heaven are subjective to the person's creation of heaven through their atman (soul). Thus a person desiring to go to a Heaven and spend it with their manifested personalized form of the Divine such as Jesus, Krishna, etc will have just that. Heaven will be a place as created by the soul and the Divine will come to them in the form and by the name of the person's choosing.
If a person only wants to go to Heaven to see family and ancestors, then this is the Heaven they will go to and the Divine will come to them in the forms of their family and ancestors. If Hell is a place they want to go, then they will manifest it and the Divine will take the necessary forms of whatever Hell is for them.
That said, homosexuals, heterosexuals, and bisexuals are all manifestations of God. Everything in the universe is a manifestation of God.
Why are there so many types of trees?
Why are some stars one color and others another color?
Why not just make kind of star, one kind of tree, one kind of person?
Apparently this isn't how things are and if they aren't that way, well everything manifests from God. God is within everything. Good and bad are subjective to the individual person. What one person may see as being good (probably because it gratifies them) another person may see it as being bad. We each experience God differently, because God is so large and vast that we can only touch and understand only small aspects of the Whole.
Thus within each person is a spark of the Divine. Each spark is seeking for a way to return back to the Whole flame. Like a river returns to the ocean, so are all of us, we just all have to take different paths and use different tools.. that is the nature of religion.
Homosexuals are yet another way in which the Divine experiences the universe and we experience the Divine. There are several stories as to why the Divine would manifest itself in Hinduism. One is that It was overflowing with creative energy that it had to burst outward and create.
Another is that She wanted to be able to have company and thus gave birth to the entire universe, but promised that it could always return back to Her. Another is that He wanted to experience Himself and thus began manifesting the universe and everything in it and by doing so could experience everything.
Another goes that the universe is like a dream within the mind of the Divine...we are all One and will merge back into the Divine Self, but right now we are all merely playing out aspects of the Whole of who we really are.
You can take any of these stories as you like them, but each of them basically says that homosexuals are a part of the Divine the same as the heterosexuals and bisexuals. We are all one, we all came from the same imitating source and we will all return to it.
Those who say that homosexuality is bad are doing so from their own subjective perspectives. For those who say that homosexuality is good then they are again saying this from their own subjective perspectives. In reality it is neither good or bad, it simply is. It is our effects on each other that determine bad or good. When Hindus greet each other they place their hands together in a prayer like manner, bow, and say "Namaste" or "Namaskar".
The meaning behind all this is "The Divine in me bows to the Divine in you" and this is done because it is believed that when we come across each other it is the Divine meeting itself. How we treat each other is reflective of how we treat the Divine....in how we treat God...since a spark from the Whole dwells in each of us.
