Pasifika rugby players supporting Folau

The Israel Folau controversy over his social media comments condemning many varieties of sinners to hell, including gays, is taking another turn. Other Pasifika rugby players, including Taniela Tupou, have waded in. Tupou says that Rugby Australia might as well sack him "and all the other Pacific Islands rugby players around the world" because they have the same Christian beliefs as Folau. Have they been backed into a corner and forced to defend their faith?
