Leave aside the Roman wars, the Greek wars and the Persian wars, the wars between various nations of Europe, wars fought between the Kings in India, all these are too far off, will just enumerate on the human life lost in wars and strife during our so called modern age: Over 25 million killed during the First World War, more then 40 million including 6 million Jews killed in the Second World War. Over 10 million Russians lay down their life during the Russian revolutions, a million put to the gallows in France during the French revolution, over a million Japanese killed by the Bomb dropped by the American on Hiroshima and Nagasaki, over a millions Algerians killed by the French during Algeria war of independence. Over a millions Chinese lose their life during the long march of Chairman Moa, over 10 million Vietnamese killed during the Vietnam-American war. Over two million killed in the fighting between the Hutus and Tutsi tribe in Central Africa,
I will refrain from quantifying, but will humbly plead with people of reason to just go into your history and investigate honestly without any prejudice the contribution of the Arab/Muslims in all the killings in human history before calling the Muslims violent and accusing Islam of preaching hate.
