Islam is the world's 2nd largest religion.
There is nothing to be scared of because those who hide behind any religion to create death and destruction for their own personal reasons aren't truely representative of their beliefs.
There are lots of scary Christians! Guys who wear white hoods and believe killing people different from them is the work of the lord. Thats one of the more obvious examples, but hardly the only one.
We fear what we don't understand. It's human nature, but don't be misled.
