Islam is a religion of violence. The proof is easy to find, look at a map of the world and spot the places where armed conflicts are happening.
It's also a religion that supports terrorism.

If it were the religion of peace, Muslims would live in peace. They have never done that. In fact, the only people who are able to keep a lid on the culture of violence has been leaders who are prepared to violent enough to stamp out any opposition.
Europe is faced with a massive problem. Does it carry on as it is doing and see the violence rise as the Muslim community rises. Or does it do it's utmost to stop Muslims coming into the West and eliminating any threat that might occur with more surveillance?
There is no option of trying to appease the terrorists by giving them what they ask for, educating them away from violence or getting Muslims to police themselves. Those methods will not work and to some extent have been tried.
Buddhists, Hindus, Sikhs, Jews, Atheists, Pagans, etc. Aren't blowing up and killing on a daily basis. Muslims are.
