I am sick and tired of people turning off their brain and blaming religion for no other reason than that is what they WANT to believe. It is a lie. The true problem is money and power and the access ignorance of the masses gives to insane leaders to acquire it.
I think ignorance is the greatest killer of mankind. A self-imposed learning disability that makes billions of people parrot back simple-minded feel-good homilies that do nothing but make sheep of nations.
LETS REVIEW RELIGION AND WAR
US vs Iraq: Geopolitical threat of Saddam acquiring and distributing RBC weapons, and oil/economic reasons.
Rwanda: Hutu vs Tutsi reprisal for perceived political assassination.
Kosovo, Chechneya, Balkan wars etc:, ethnically motivated geopolitical nationalist pro vs anti communist/capitalist ideology towards independence & statehood.
Vietnam: US vs Russian expansion.
Korea:US vs Chinese expansion.
WW2: German expansion.
WW1: Perceived assassination of Ferdinand.
American civil war: Liberal democracy vs. republic issue.
American revolution: National independence from England.
Europe 1600-1800: Wars of accession, land, and independence.
Rome 300BCE to 800AD: nationalistic expansionism, and conquest for the sake of conquest.
Greece: see "Rome" above.
Even the Islamic vs Jewish problem has more to do with land, than religion. If Jews would just go away, they could worship somewhere else (like Alaska or Antarctica I guess). The Arabs don't really care, they just want the land, and for Israel to go away.
That accounts for BILLIONS of casualties, almost entirely based on nationalistic expansion for economic reasons, to gain land and power, often directed by charismatic leaders followed by people who fail to think critically.
So, do you want to compare "The Crusades" or "The Inquisition" to 4,000 years of greedy, power-hungry megalomaniacs leading, dismembering and murdering billions of humans simply because they can? Stalin? Ghengis Khan? Napoleon? Hannibal? Did the Vikings engage in conquest in order to convert the masses to another religion?
Yes, you can blame the few thousand deaths in the Crimean war, the Crusades, and perhaps some of the Ottoman/Persian conquest on religion, but that is a laughable comparison to the true motivation for war: MONEY and POWER. And in fact, where there is a religious reason involved, it is STILL driven by leaders struggling for POWER over masses of morons, because the people provide the means for them to do so in the first place.
Stop blaming "religion" and start taking responsibility for your own intellectual laziness and lack of humility, i.e. pride. These are the tools the masses provide the morally bankrupt and insane leaders the means to murder millions at a time, and impose economic slavery for their own personal benefit, whose only religious motivation is to make themselves into gods.
