@SoloSenior Haven't you thought that the creators of these websites have an agenda and their aim is to distort the image of Islam? Islam is the second largest religion in the world, if killing is part of its practices, you would have been dead by now. I'd assume that you are an intelligent man. Therefore, I'd encourage you to do your own research and to do not make the internet your main source.
Why do terrorists tend to be Islamic? Who else would just go into a theater and start killing people. Maybe we're not all dead yet but make up of the refugees is a red flag in itself. The majority of refugees leaving a war torn country is always women and children. Not these refugees 3/4 of the million refugees Germany took in 2015 are men. Once the refugee movement has stopped the attacks from within countries that took refugees will be huge!
life isn't about impressing and pleasing others, life is all about being yourself, expressing yourself the best way you can, and being a better person... trying to always improve yourself for your own sake
