First off, using Biblically source references to prove the Bible is circular reasoning. Secondly, everything referenced in the article is from prior to the turn of the century/millennium, and as such is out of date, before we even considered that it's been cherry picked. You basically have used 15th century scientific papers in the 18th century to prove that the geocentric model is true and not the heliocentric. Even pro-LBGT medical professionals will tell you that there is no singular gene for homosexuality. And yes, God can change them, yet it is extremely rare that He does, even among those who desperately wish to be changed, which indicates that He has made and keeps them homosexual for His own reasons. Thus, it is man's folly to presume that he knows better than God and declares homosexuals to be against God. Also, there is an inborn predisposition to theft. It's called kleptomaina. It is not common, but then again neither is homosexuality.
People who have heterosexuality can manage it too. Your point does nothing to take away from the argument that homosexuality in an innate trait. And again, with the double posting responses for the same post? Do you fear the edit feature? Try telling that to other anti-LBGT Christians. That said, if God created homosexuals, which He would have to since He created all our innate traits, frequent or rare, then He has a reason, and there is no real evidence that it is not the equal of heterosexuality.
If God can change our sexual orientation, can you ask him to make me bisexual? It will double my chances.
