Forkbender a dit:
Because if Islam grows, there will be fewer people who are non-muslim, which is simple math.
The situation isn't that simple though. Currently most non-muslims do not oppose Islam. But when Islam becomes more prominant and then dominant in the West, a larger percentage of the non-muslims will start to feel uneasy about it and there will be more opposition (in the media etc.).
Proof that muslims beheaded a cartoonist.
We've got reasonably good (but expensive) security experts preventing such things from happening. Not a cartoonist but a film maker and writer was killed sacrificially on the streets of Amsterdam though.
Islam is a religion, it is not a collection of quotes. Religion without practice is just words and does not embody the true Islam.
There is disagreement as to what is true Islam, but as mentioned before, the Quran takes a central role in Islam. And the Quran is a collection of quotes. I already cited scholars who explained that Islam is the most scripture-based religion of them all. That's why we have a problem.
Show me where those quotes of you are reflected in their common practice.
Not "their". We're not talking people here, but a religious system. The impact that this system has on these people and on the world around them. We don't hate the muslims, we feel compassion for them, for the dominant religious system is depriving them of genuine freedom and happiness. Yes, muslims can be happy, but it's not necessarily to the credit of the religion.
Danger occurs when a person starts reading the Quran fanatically, say, a couple of hours a day (like I did with the Bhagavad-gita a decade ago). Then the mere quotes (and many like them) will be read over and over again. Such people can become dangerous to themselves and their surroundings.
For both reasons, both the misery and the danger, we may tell people to take a more cricital look at their religion. All religions. There seems to be a heavy taboo on discussing Islam. One can write anything about Christianity and there will be no objections. I've been critical of Hinduism and there were no objections. But if I'm critical of Islam I'm "playing nazi games"? :?
