I had no idea that FCA was anti-gay. I joined in high school because all of the cutest boys were in it. I don't remember anything else but cute boys.
I didn't know it either until I started reading more about Chic Fil-A. It was made up of the kids who went to "good" churches and had the best parties. The snake handlers were in another Christian club--they used to call the FCA "Fellowship of Christian Alcoholics."
