Religion has been demonized by those who use it as an excuse to do whatever they want. Atheism has been demonized in the same way. Neither is a logical belief/non-belief because there is no empirical evidence proving the existence or non existence of 'God'. The agnostic position is the only one that actually makes sense. There is no agnostic extremism. There isn't very much atheist extremism. There is a whole damn lot of religious extremism, including many more than just some followers of Islam.
When the IRA and the UDF were killing civilians left right and center during the height of the Irish troubles, they were the terrorists and they were fighting largely about religion. Ditto the Catholics killing the Cathars in the south of France. Shea Muslims fighting Suni Muslims. The European Christian original settlers in the Americas killing the natives. The Crusades. Nation vs Nation does not equate to religion vs religion - most of these were civil wars of a type.
There's a whole lot of history that shows that religion just provides another excuse to get rid of what you don't like. Usually what one group of people doesn't like is something that's different to them, this includes all forms of discrimination eg racism, homophobia, anti-disabledism, etc etc. Even the micro example of the kid that gets bullied at school cause their clothes are different, or their hair is ginger, or they're short or tall or fat or bespectacled or smart or stupid: the majority of a society looks to punish deviance from the norms of that society. Genuine tolerance is a rare thing to find. Religious intolerance is just another part of the condition from which human society suffers.
To whoever said that the British and American invasion and occupation of Iraq and Afghanistan are not about religion: the 'terror' which those nations' governments claim to fight is that of Muslim extremism, so religion plays a part.
Conflict is a part of human nature, it's not all religion's fault or atheism's or the fault of people who prefer cheese to butter. It is something which mankind has engaged in since the very beginning. Modern motives for war almost always include a warped type of political morality, and/or financial greed.
As far as creationism vs evolution goes, i'm firmly in the evolution camp. There's a lot of scientific evidence and a logical well presented theory. I could be wrong, but evolution seems far more likely to be right than creationism which is at best an overly simplistic interpretation of a particular segment of mythology. [Mythology is absolutely the correct word to use, and does not in its true sense carry anti-religious connotations]
I don't find Christianity to be a particularly believable faith. E.g. its original form, Roman Catholicism, teaches that during the transubstantiation of the host the bread/cracker/wafer actually becomes the body of Christ and the wine his blood. Not metaphorically, quite literally. As in, every time a Roman Catholic takes mass, they believe that what was formerly just a wheat based snack magically transforms into a piece of the body of a 2000 year old dead man, which they eat. Any RC who says they do not believe this is not true to his/her faith. Anyone who does believe this is, in my opinion, having a psychotic episode.
However, 'God' and evolution can be equally true. I believe evolution for the reasons stated above (among others) but that doesn't exclude all spiritual belief. Could there be a higher power of which there is no evidence? Absolutely yes. Is there one? I don't know, but if I'm ever presented with an argument for the existence, which I find indisputable then yes, I would gladly believe. Equally were I presented with an argument which categorically disproves the existence of 'God', I'd believe that. But it'd have to be some mother-sturdy type of argument because as it stands hundreds of brilliant minds have tried to prove God, and as yet each has failed.
Peace.
