Apparently your comments are not based on any scientific studies.  The so-called 'thousands of years of human understanding' is faulty.  Shepherds of domestic sheep have known and observed for thousands of yeas that their rams often sought out other rams for 'companionship', even when surrounded by many ewes.  Every other species also demonstrates members who are 'homo-sexual'.Today, there is an abundance of material concerning 'homo-sexual' animals and humans.  Sex is not just for procreation, even among animals.
 
Homosexuals are attracted to each other because of Love the same as Straight couples are.  They are not LUSTFUL more than other humans.  You do not speak for God----who created both animals and humans with very similar sexual attractions.  It is the official church, with its heretical antipathy for SEX to begin with, wrote teaching, back in the days when most Christians were illiterate, stating that sex is ONLY good for the procreating of children within marriage.
