The homophobia displayed in many of the comments is appalling.  
I wish that those who are so concerned with saving the souls of others would become more concerned with their own souls and leave the rest of us to God and our consciences.
No gay person is pushing anyone else to be gay.  If some think or believe that homosexual sex is sinful, they should not engage in it.
The fact is that none of us knows for sure what God thinks.  We choose to believe what we will.  But believing is not the same as knowing.
For those who insist on following the Scripture, there is much more written in Scripture about treating others with love and respect than there is about homosexuality.
So, stop, already.
