When did Islam become the bad guy?

[Shiranu]

Not a fair comparison.   Christians have been around a bit longer.  They've had more time to get some killing in.  We need a proper graph, not a pie chart.

Accuracy aside (the Muslim part should be about 10% instead of 5% ), you realise it says 20th Century killings, right?

Islam became the bad guy when Gabriel told Muhammad to slaughter the jews from the Banu Qurayza.

Wikipedia has ex muslims setting the record straight,it's easy to see what was written by ex muslims there.

800 men and  woman had their heads chopped off by muslims.

If muslims only fight in self defence can any apologist explain this-

Muhammad was a warlord,take note of his first expedition which was highway robbery to relieve muslims from poverty-

We could read Islamic texts to see how the jews pissed the muslims off-

Umar expelled the jews and Christians from Hijaz.
When Allah's messenger had conquered Khaibar, he wanted to expel the jews from it as its land became the property of Allah,his apostle,and the muslims.
Allah's messenger intended to expel thejews but they requested him to let them stay there on the condition that they would do the labor and get half of the fruits.
$Profit Mo told them-we will let you stay on thus condition,as long as we wish,so the jews kept on living there until Umar forced them to go towards Taima and Ariha.

Islam became the bad guy at the moment of it's inception.  The same for all other organized religions.
