"Islam is a religion of peace."
Actually, no, it's not.
Here's what the Quran says about non-Muslims: "Kill the unbelievers wherever you find them"
The Quran gives fairly explicit instructions about how Muslims should deal with non-Muslims:
First, you should try to convert them.
If that fails, enslave them.
If that fails, kill them.
If that fails, drive them from your lands.
If that fails, force them to pay protection money.
In many Islamic countries, conversion from Islam is punishable by death (as the Quran teaches). In 2006, Abdul Rahman was sentenced to death for converting from Islam, but sentence was commuted after international pressure mounted.
And who can forget poor Salman Rushdie? He's been in hiding ever since being sentenced to death for making fun of Islam (the Quran teaches that those who mock Islam should be killed).
Sam Harris sums it up well:
"As a matter of doctrine, the Muslim conception of tolerance is one in which non-Muslims have been politically and economically subdued, converted, or put to sword."
The small number of Muslims I have known seemed like nice folks, but I think this is because (fortunately) they do not follow the Quran very closely.
Addendum: This is so good, I just had to make room for it. It's a quote from Mahavira, the founder of Jainism.
"Do not injure, abuse, oppress, enslave, insult, torment, torture, or kill any creature or living being."
Beats the pants of the 10 Commandments or anything in the Quran.
