Equality Rider: “I am not a sinner”

From a Gay365.com article regarding Equality Ride’s visit to the media, I mean campus of Union University:

Dawn Davridge said that she and her partner, Kathryn Davridge, were expelled from Union two years ago after administrators found out they are lesbians; and in a relationship.
“I fell in love with my best friend,” Davridge told about a dozen students who gathered to hear from the riders. “I am not sick, and I am not a sinner. Two years ago, our story was suppressed.”


The terms sick and sinner have been in numerous quotes from Equality Riders. I assume that this is one message designed to be a take away point from the entire effort. Seems strange to hear someone who is claiming to come from a Christian perspective saying, “I am not a sinner.” To anyone who reads this blog and is up to date on gay integrative theology: When did homosexually attractions come into the human condition, before Adam and Eve fell or after?
