Holmes says:
So let me repeat this... the answer has been given. The harm of homosexuality is that it is considered wrong. Whether from God or just plain people that feel that it is wrong, that is the source. Homosexuality is obviously different from heterosexuality in that it is same sex coupling versus opposite sex coupling and one is felt right while the other is felt wrong.
If that is an answer, I must assert that it is an inadequate one. What you are doing is called argumentum ad numerum. It is the fallacy that if many people believe a thing then the thing must be true. There's also a nice tang of argument from personal credulity. You "feel" homosexuality is wrong and a lot of other people do too, so it is wrong. That's two logical errors in one statement.
You may also seem to claim the following:
1. God has stated that homosexuality is wrong.
2. God is the final authority on this, as he is in all things.
3. Therefore, homosexuality is wrong.
This (if it accurately reflects your position and I continue subject to that) is a better argument and in response I would have to address the second premise. Before this argument could be accepted as factual (as opposed to being valid) I would have to see proof of #2. Feel free to provide it if you can, starting with proof of the being in guestion's existence.
