The new testament indeed condemns homosexuality, but the sin is what is condemned, not the sinner. Someone who chooses to maintain a life of sin, as defined in the bible, is not trying to follow jesus and is therefore not represented in OP. A sinner who seeks biblical salvation would be a homosexual who seeks redemption through Jesus, which is what the OP depicts.

Again, the OP is wrong because Jesus would not abandon or condemn his followers for rejecting a sinner. Rather, he would embrace the sinner specifically to lead them away from sin, and teach his followers to forgive and embrace the sinner to also lead him away from sin.
