Yes it is. Islam actually preaches that the Muslims should invade and take over the world. There are over 40 Islamic countries around the world. Each of which was taken by force and millions of the original inhabitants were killed and millions were converted by force.
"It is not for any Prophet to have captives until he hath made slaughter in the land. You desire the lure of this world and Allah desires for you the hereafter and Allah is Mighty, Wise. Now enjoy what you have won as lawful and good and keep your duty to Allah. Lo! Allah is forgiving, merciful." (Koran 69:30-37)
"In order that Allah may separate the impure from the pure, Put All the impure ones (Non-Muslim), one on top of the another in a Heap and cast them into Hell. They will be the ones to have lost" (Koran 8:37)
These verses instruct the Muslims to invade, destroy, kill and convert by force, something they have done for the past 1400 years.
They will try to argue about the killing that went on in the name of religions hundreds of years ago, but that's the whole point, they are the only religion that is still in the killing mode. They (Islams, Muslims) are truly a bunch of losers!!
