Most Gays are smart enough to know that the official church cannot PROVE scientifically, medically, or psychologically that either Gays or their actions are disordered.  The church continues to use the Bible as the basis [and then any church teaching supposedly based on the Bible] as the main proof for the church's argument against homosexual acts.  

The church tried to use the Bible, centuries before to prove that Galileo was wrong in his assertions---that the sun is the center of the solar system.  The Bible was not written to be a 'proof' text to support that the earth is the center of the solar system, then.  And the Bible is not a 'proof' text to support that either being a Gay or to engage in homosexual acts is sinful now.

The church either needs to use forensic medical science to prove its points.  If it can't, the official church needs to stop making a fool of itself.
