The LORD examines the righteous, 
"Skeptics often raise the spectre of religious wars and other alleged
‘fundamentalist atrocities’, implying that if only humanity were to grow
up and face life without God, we would finally attain some 
peaceful
utopia. However, it’s important to note that religion had nothing to do
with the vast majority of wars, e.g. the Hutu-Tutsi war in Rwanda, the
Falklands War, the Vietnam and Korean War, WW2, WW1, the Gran Chaco War
in South America, the Russo-Japanese War, the Spanish-American War, the
Franco-Prussian War, the Crimean War, the US Civil War, the Napoleonic
wars, the Wars of the Roses, the Mongol wars, the Gallic War, the Punic
wars, the Assyrian wars … etc.
but the wicked,
those who love violence,
He hates with a passion.
Psalm 11:5 NLT
It is true that some Christians have used their own swords instead of
the counsel of ‘the sword of the Spirit’ (i.e. the Word of God) to
combat what they saw to be evil.
---However, the number of deaths in the
20th century alone due to evolution-based philosophies such as Nazism
and Communism far outweigh those caused by ‘religion’ in all centuries
combined. Furthermore,
*any professing Christians who murdered others
were acting inconsistently with their professed faith,
*while Hitler and
Stalin were acting consistently with theirs."
