Oh really? I have non Christian friends, although none of them are gay. You know who else associated with morally undesirables? Jesus.
Luke 7
33For John the Baptist came neither eating bread nor drinking wine; and ye say, He hath a devil.
34The Son of man is come eating and drinking; and ye say, Behold a gluttonous man, and a winebibber, a friend of publicans and sinners!
35But wisdom is justified of all her children.
