It is also ironic that the main crime Christianity is often accused of committing was in response to Islam.
(the Crusades and the Spanish Inquisition)
The muslims controlled Spain for 800 years!!!!!!!! Throwing them out and keeping them out required the Crusades and the Spanish Inquisition, otherwise the evil of Islam would have spread over the entire world.
It is just unfortunate for the American natives that the New World was discovered exactly when Christianity was forced in self defense of its very existance to become rather extreme.
Most of the carnage of the New World was unintentional. Europe brought over smallpox and other diseases which devastated the native populations. One wonders why the New World diseases did not do the same thing to Europe .
