You need to actually study the Bible. Actually study it, not just listen to what others tell you. The original scriptures don't actually say much of anything about homosexuality.
The words translated into homosexuality wasn't even present in Bibles until more recent times.
For there are eunuchs who were born that way, and there are eunuchs who have been made eunuchs by others--and there are those who choose to live like eunuchs for the sake of the kingdom of heaven. The one who can accept this should accept it.'
Matthew 19:12.
These are the words of Jesus.
In the Bible you will also find support for polygamy, sexual slavery, incest, and forced marriages.
