Unfortunately, when one holds the bible to a standard of inscrutability and a standard of absolute, objective truthfulness, that standard is based upon strongly-held personal (and subjective) notions. It removes the possibility of subjecting the texts to the type of critical scrutiny that take under consideration differences of language, and culture that simply do not make an easy translation from an ancient understanding to a post-modern understanding.
First of all, we need to understand that, even though the bible condemns homosexual acts, it does not condemn homosexuality. As I asserted before, the ancients did not understand the homosexual act as a natural expression of a natural orientation. They did not understand that there was such a thing as a homosexual orientation. They thought that all people were oriented toward the opposite sex, so, of course any homosexual act would be considered to be "unnatural." Today, our medical experts know differently. The bible cannot condemn what it does not know exists.
Second, you need to understand that, since God didn't write the texts, it's not really purely "God's standards" that we're dealing with here. We're dealing with God's standards as understood through the cultural. lingual, and educational filters of the writers. Therefore, those "standards" are highly-biased by what the writers think and understand.
Third, when we hold the standards of the bible in stasis, not making allowances for scientific understanding or cultural differences, the texts very quickly become irrelevant -- and even harmful! Case in point, people of the 18th and 19th (and even 20th) centuries used the biblical texts to justify slavery and discrimination against blacks. You see, it's not simply a matter of "what the bible says." It's a matter of "what the bible says in light of what we understand as reasonable."
With regard to your last 3 sentences, I find it admirable that you find hate deplorable, but you need to understand that "disagreeing with homosexuality" is fine, so long as a judgment -- especially a judgment made upon rather arbitrary biblical standards" -- does not enter the picture, since, as i've shown, the texts are not nearly as absolute on the subject as many of us have been taught to think. Holding people to arbitrary standards based upon ancient scientific and cultural understanding is an opinion -- and it's ultimately a hateful one, because it does not allow for the validity of the other person's values, assuming that yours are superior.
Again, before you begin teaching and preaching, IMO, you (and the rest of us) would benefit from your further education in this area.
