Christianity offers a gospel of love, of God's love for us, our love for God and our love for one another. This is the central message.
Yes, if you look hard enough you can find passages in the Bible which condemn homosexuality. There are passages in the Bible which condemn those who wear clothes made from mixed fibres or don't cut their hair in the required manner. Some obscure OT passages describes brutal events which appear to be approved - genocide and rape - while the OT and NT say some pretty negative things about women.
The Bible is written by men, translated by men, interpreted by men. There is a view that says the Bible is a reflection of the word of God, not directly the word of God. All ages should take from it the broad message, but all ages have trouble with the detail, and the Bible-thumpers who argue "the Bible says" + obscure quote + "therefore you must do / not do x else go to hell" - these in my view have miss-read the totality of the Bible and missed the important, central message.
What is important is the way in which you live your life. Live your life with love: for God, for your neighbour, for yourself. These things determine the fate of your soul, not whether you happen to be gay or straight, or whether you have red hair or a big nose.
