Nonsense.
We are all going to Hell, by default. Any sinner who accepts Christ as Savior can be redeemed by His blood. Even a homosexual sinner!
All sin (except for blasphemy against the Holy Spirit) can be forgiven by God. Aside from that single exception sepcifically noted in scripture, there's nothing unique about any sin which makes it less forgivable than any other.
Thus, the sin of homosexuality, among countless others, when committed by a Christian, can be forgiven, and such a person can thereby escape the fires of Hell through the grace of God.
It is the height of arrogance for anyone to usurp God's role as the sole Judge of a man's heart.
And, fortunately for all of us sinners, hysterical pronouncements to the contrary don't override God's mercy.
