No you don't.So to understand the West, never mind Western poetry, we need to understand Christianity.
Any religion imprints itself. If you were born in Iran you'd have been raised Muslim.Christianity imprints itself upon us as children and no amount of subsequent reasoning makes any difference.
I'm pretty sure my alcoholic abusive mother had a lot of love for me.After all it is our mother right or wrong. We only get one mother and no one ever loves us like our mother. And so with Holy Mother Church.
Marxism is NOT a religion.And it takes a religion to beat a religion. And I noticed in Oz in the 40s and 50s so many ex-catholics became marxists.
Where is your evidence for this? Christianity is still the dominant religion in the west and will be for quite some time. Only immigration in Europe is changing that. Also Separation of Church and State isn't Christian (AGAIN look up Treaty of Tripoli Article 11.) Seriously, you sound like a fundamentalist calling for a religious war.And today we see that it is Islam that is beating Christianity. We see churches being turned into mosques. We see that the Common Law based on Christianity is being slowly overtaken by Sharia Law. We see that the Christian separation of Church and State is being overtaken by the unity of the Mosque and State. We see that Christian equality under the Common Law being overtaken by inequality under Sharia Law for Jews and dhimmi, infidels and women. We see Christian monogamy being overtaken by Sharia polygamy. We see women stoned to death and child brides.
