first of all i wanna say, even though this is a good question.
but, you did the big mistake about "half-christian"
there is no such express.
half-christian is not count into christian.
and when you mentioned "christian" must to refered only "christian" or 100 % christian ofcuz, there are (bad, good) (fake , real) for separated them.
now i would like to asnwered you question.
i do agreed with "roi g"
"John 3:16 God so love the world............. "
no matter wether you are gay or not gay. God is still God.
and God still love you. and you still his child.
the most important thing is think right, do right. love others as yourself.
so, gay or others are never discriminated or eliminated from sosiety.
