People may choose not to be Christians. If they choose otherwise, they must accept the moral standards associated with their choice. People outside the faith should not be held accountable for standards applied within the faith. You are right, who is included or excluded does say much about who Christians are. Sorry, but I couldn't care less what psychology says on the subject. Habitual , cherished homosexual behavior is a sin. You may not like it, but then you do not determine what I believe. No matter what you think, the Bible says what it says, and you nor anyone else can change that. I and my fellow believers have the absolute right to worship as we choose, and the absolute right of freedom of association to include, or exclude, whomever we choose from fellowship with us. You may not like that, but there are many things in life that we do not like. I am not asking you to believe as I do, nor am I attempting to sway your opinion on any subject in any direction. It is what it is and all the argument there is possible will not change Christian morality. The only caveat is if a human gene is identified that without question causes homosexuality in every case where it is present, I will reconsider the issue
