Islam is a religion of Peace and YES also tolerance but you may not believe so because like a lot of people their interpretation of Islam or Muslims is related to the Taliban, Al-Qaeda and Osama Bin Laden and others who give Islam and its followers a bad name. We like other peoples and countries strive for peace, happiness and prosperity like others but we are just misunderstood by those whose fears shroud the truth.
By "pure", I was referring to adopting practices from other religions or philosophies. I wouldn't expect the Mullahs and Imams to accept certain aspects of daily life that some practice simply because they just don't seem acceptable to many theistic religions, IMO. From what I have read and heard, true Muslims have rules that they're required to observe (like most other religions) and while it's normal practice for the leaders to be very conservative, it doesn't sound particularly tolerant from the perspective of someone on the outside. When the conservatism is taken to extremes, more and more is restricted. Not criticizing, just an observation.
The fact that Judaism, Christianity and Islam (listed chronologically) are as similar in many ways is why I have a major problem with all of the violence between them. Even during the Crusades, they were killing each other in the name of the same God- Eloh(Elohim) and Allah, right? After 9-11, I wanted to find out why this kind of thing could happen, although after seeing the Taliban destroying ancient Buddhas and artwork in the '90s, I was sure they didn't represent mainstream Islam and at the time, I knew next to nothing about it. Al-Qaeda and OBL have their own version, too and one thing I don't see is mainstream Islam doing much to quash the extremists. The majority seems to be just standing by as spectators. If a family has mostly peaceful members and a couple of rebels, in many cases the family will discipline the bad ones. I'd like to hear a definitive answer to why the extremists are allowed to continue with their destruction of the "outside world's" view of their religion. Even the Catholic Church ex-communicates people if what they do is bad enough (pedophile priests being an apparent exception).
Unfortunately, most of the available information is slanted one way or another and I don't see much reaching out, from any sides. Unfortunately, I think the whole "kill what is feared and fear what is not understood" problem will still be with us for a long time.
