You say melting pot/multicultural as if they're the same thing. They're not- they're opposite concepts. It's an understatement to say that Europe has had issues with tolerance, and certainly at times, religion has played a key role in that, but what about now? The continent's more secular than it has ever been in the past and certainly more so than Christian America, so why the continued trouble with tolerance?
While melting pot and multicultural perhaps are opposites, they can co-exist, like black and white. Sometimes the US reminds more of a salad bowl, ie a mix of melting pot and multiculturalism, hence the "melting pot/multicultural".
If you look behind the european secularism, there still is a lot of religion and culture in play that have evolved for more than a thousands of years. Secularism is describing how the church have gotten a less prominent role in the public, but often fail to detect spirituality and new forms of religions that perhaps can replace the loss of religion in public. Talking about the intolerant culture of europe, feudalism and terrorital wars perhaps have played a role, but, as I said, IF any religion have wrecked europe, it's christianity, not Islam.
Anything is possible in the future, but if widespread imposition of sharia is low on the list of things I should worry about, then a devolution back to inquisition-style Christianity is way further down that list.
I doubt Christianity really fueled the slave trade. Yes, slave-holders and Southern preachers tried to find justification in the Bible for slavery, but would they have still involved themselves in slavery if they weren't Christian? I think probably so. On the other hand, would the abolition movement have had the success it had were it not for Christianity? I think probably not.
I already listed out the two distortions about Islam I've heard and they are relatively rare. Most people bend over backwards to be accepting and tolerant. Considering we had just suffered the worst attack on our soil in our history in the name of Islam, we have been remarkably restrained in our treatment of Muslims. Retaliatory attacks against Muslims have happened, but they have been rare and we have not been hesitant to punish such crimes.
I can understand the american reaction to 9/11. That was truly an horrible happening and you have all my condolences. One of the damages assaults like this can do, is to trigger irrational thoughts. It's like someone gets robbed, and develops a fear of strangers. Vague and unclear use of the term "extremists" reminds of this.
However, many have talked about the actions and desires of extreme Muslims. It's actually quite difficult to exaggerate on the horrors of extreme Islam because the truth is so horrifying. I mean, we're talking about people who will riot and murder over a cartoon or a book.
Funny how some of those insulting cartoons were published in egpyptian newspapers, without anyone rioting. Those stories have much more in them than you are expressing here.
You're talking about the foreign policy doctrine of realism- that it's better to support a dictator who at least keeps things stable than to have him overthrown and replaced by thugs who destabilize the region and threatens other countries including our own. Case in point- Iran. What's preferable? Having the shah or the ayatollahs? Such foreign policy doctrines are debatable, but they have nothing to do with settling religious scores (at least on our end). Besides, more secular Europe doesn't exactly have clean hands when it comes to supporting dictators.
This is what dictators want you to think, that they are the best one to run the country after all, and they all point at Iran to scare you.
Europe is corrupt as hell, yeah. We buy food with guns from african dictators, with the help of a dozen of mafias, and get asylum refugees in return, who we exploit, and then accuse of extremism when they find a purpose with their meaningless life in a local mosque. Europe is great, isn't it?
