On or about 1972 the medical professionals in the area of psychology removed homosexuality from the list of abnormal behaviors. The change did not occur due to any new or relevant data, rather it came about based on the strong political pressure of a few.
Oddly, the real medical world will tell you that anal intercourse always causes injury and exposes both partners to chronic, contagious and deadly diseases. For these reasons God severely condemns anal intercourse (hetero or homo). Those that glorify, condone or ignore the results of anal intercourse hate gay men. Why do you hate gay men... In this case religion has been more objective and more caring than alleged scientists.
