Protestant Bradman Vs Cathlolic Aussie team-mates

I find it very interesting that the differences between Bradman and his team-mates also had a Catholic-Protestant angle. Despite the fact that the Australian team was world-beater the differences within the team are well-known.
Bradman's phenomenal success caused jealousies among team-mates who watched as he was showered with financial gifts and remained a private person, aloof from the team. Fine. But now read this:
"This disaffection was strongest among a group of players-Jack Fingleton, Grimmett, Stan Mc Cabe, Ernest McCormick and O'Reilly-all of IRISH origin and Roman Catholics and a different political persuasion to Bradman, who was a Protestant, and essentially a patriot and monarchist, a tee-totaller and a non-smoker. This group suspected it was discriminated against by Bradman.
When he was out for just four in his last test innings and could not achieve a test average of 100, O'Reilly and Fingleton who were in the Oval press box could not conceal their delight, says Simon Wilde in his book "Number One: The world's best bowlers and batsmen'.
I never knew this. Though Bradman praised O'Relliy through out his career. He called his team-mates when Mc Cabe was hitting his famous century against Larwood during Bodyline saying ' Come and watch you will never see such an innings'.
