No you haven't.<quoted text>
Already proven homosexuality is a sin, you don't have to accept it but it still doesn't change God's word.
You've shown that abusive and coercive homosexuality is a sin, but you haven't shown a single verse where the Bible condemns loving, committed same-sex relationships.
You're distorting God's word to support your preexisting bigotry. The Bible simply does not say what you think it says. You are flat out wrong.
