The Fellowship of Christian Athletes, the Salvation Army, and the Paul Anderson Youth Home.
The Fellowship of Christian Athletes religious requires its employees to refrain from “homosexual acts” and it doesn't get much more discriminatory than that.
The Salvation Army has had a long history of discrimination and once publicly claimed gay people “deserve death”.
The Paul Anderson Youth Home teaches children that same-sex marriage is a “rage against Jesus Christ and His values.” (Jesus never once says anything about it in the Bible)
Chick-fil-a no longer donates to these organisations, but they stopped BECAUSE of the backlash, not because the backlash was in any way ill-informed to begin with.
