Many schools of thoughts in the Eastern religion believe in the theory of multiple lives. Every humans in this world are born for a purpose and within his/her life time on earth, he/she must fulfil that purpose, failing which he/she will be born again to learn the lessons and to perfect the purpose.
Homosexuality is the result of the purpose not fulfilled.
Leviticus 18:22;20;13,Romans 1:26-27 and Corinthians 6:9-11 support the general anti-gay stigma.
Answer:
Christians(in theory, not all necessarily do) believe that God does not create a homosexual, he creates a heterosexual who chooses to "disobey" him and live as a homosexual. Homosexuality is seen as a sin. However, humans are not to judge the 'sinner' for this is the job of the Lord. This is the theoretical belief of Christians in regards to homosexuality. Other main-stream religions are considered to have the same view.
