Alright, I got the basic gyst of CAUSA's arguments against Islam and why it is evil. The stuff about the crescent is just childish bull crap. Rational people don't pass judgement on a religion because it's shape is "funny" or worshipped by some cult that has nothing to do with the religion. The Nazi swastika came from some Tibetan monks, does that mean that the Dali Lama is a Nazi?
In any case, moving past that. Here are the main claims of the Islam is evil camp:
* Muhammad was violent, launching raids against peaceful carravans
* Muhammad was anti-Semitic, seizing the lands of Jews, killing the Jews and selling them into slavery
* Muhammad married a 9-year-old and is a pedophile
* Muhammad had several wives and thus practiced polygamy
* Muhammad was a violent man, not like Jesus who was peaceful
I have consulted with three history books on this and I'm going to say my impressions of Muhammad and Islam and this whole debate.
Firstly, I would say that it's not so relevant what Muhammad did back then. The question is: what is Islam now? Islam has behaved with far more tolerance towards non-Muslims than has Christianity. Who did the following?
The Inquistion
The Crusades
Religious War (i.e. St. Bartholomew's Day Massacre)
Sending out missionaries to accompany armed invaders on most countries of the world
Not Muslims. That was all the doing of Christians.
Although Muslims taxed non-Muslims, they didn't do Inquisitions on them, as the Spanish did to the Moors and the Jews, and Europe did pogroms on the Jews, so don't give me any bullshit about how mean the Muslims are. Mind your own glass house first.
OK, moving on. So the question is: how have Muslims acted recently?
The answer is that Islam is diverse and that it's dumb to use a blanket statement to try to cover them all. Central Asia, Bangladesh, Malaysia, Indonesia, and Turkey are all Muslim. Several of these countries are democratic and do not sponsor any terrorism against us. We get our countries oil supplies from Saudi Arabia and Kuwait, so how jihadist can they be? We also have very good relations with Jordan and Egypt, so again, where's the jihad? Oh right, there is none.
In my opinion, Islam is one variable among many: including the culture of the nation its in, the economic position of the country it's in, the geographical position of the country it's in, and so forth. In other words, it's dumb to just make blanket statements about Muslims, since Muslims are a diverse group.
So the relevant thing here is not what Muhammad did back then, but what Muslims are like right now. The answer is that you can no more say what Muslims are like right now, then you can say what Christians are like right now.
You have good Muslims and bad Muslims, good Christians and bad Christians. That's it.
