Islam divides the world between the believers (Ummah) and the conquered areas under Shariah law versus those who have not submitted to Islam, called the house of war.
Islam calls for death of the infidels, making spreading Islam the highest good, so killing a few is moral if it scares others into converting to Islam. The Koran calls for committing atrocities to scare others into converting so the same doesn't occur to them, repeated calls to cut off heads and fingertips to that the town you approach has heard how horrible the Muslim army is and submit to Shariah law (second class status for Jews and Christians, less for Hindus and Buddhists).
We are in a world war of resurgent fundamentalist Islam versus everyone else. That's why they are beheading Buddhist school teachers in Thailand, blowing up public transportation in Russia and China, threatening bars and nude swimmers in the EU.
It doesn't matter if a Hindu group says we're holy and you're not and we'll sit in this ashram and do whatever. They aren't killing their members, and more importantly, they aren't killing non-members for not being members.
ONLY ISLAM is doing this, and it does this per over a hundred verses in the Koran calling for Islam to be spread by the sword, conquer the world until all submit (the meaning of the term Islam). This is compounded by Mohamed leading several war parties to do exactly this. The peaceful verses in the Koran are irrelevant because later verses negate the peaceful ones, as you see with early verses saying don't be drunk replaced with "no alcohol" that stands to this day.
Only Indonesia converted through missionary activity, every other nation was conquered by Islamic armies who forced the religion upon pain of death or a hundred little laws that privilege Islam over every other faith. (No right to own weapons for self defense, half the worth in court and inheritance, can't marry a Muslim woman, murder by mob if someone says you defamed Mohammed).
There is a very dangerous tendency of liberals to blame extremism, then point to the Tea Party, blame religion and point to Christians, while ignoring Muslims calling for the death of the infidel and actually killing people. Half of Muslims in the west support Shariah law, a quarter support suicide bombings. That's not a peaceful movement, and blaming the Christian conservative as the source of the world puts civilization at peril because you can't name the enemy killing you.
