There is a scene where John the Baptist kisses Jesus on the lips, but it certainly isn't to imply that either Jesus or John are gay or bi. The sequence is right before Jesus goes into the wilderness for forty days, and John emotionally hugs and kisses him before warning him that the devil will try to deceive Him in the desert.
We need to be accurate when we protest things that are an attack on our faith. Saying that Jesus was portrayed as gay in LAST TEMPTATION is not accurate. There are plenty of things wrong in that film, but that isn't one of them.
