Orthodox Christians know all too well about persecution.
And have been bearing the brunt of Islamic Jihad on the Christian world for the last 500 years. European Catholics/Protestants have had no worry from Muslims ever since they were repulsed from the Gates of Vienna. Within the last 125 years European Catholics have sold out the Armenian orthodox, the Greek Orthodox, the Balkan Orthodox to the Jihadist Muslim masters of genocide. By European Catholics I mean the Vatican and governments of European Catholic nations. Latest outrage being Euro-Catholic non support for Serb Orthodox in their battle against Albanian Muslims. And their aggression on Serbia via bring the USA into the war to bomb Serbs into submission.
