I think we should ask some questions about Political Islam and that should not be an attack on all Muslims. There are moderate muslims but there is no moderate Islam.
When analysing Islam we have to determine the reasons for their behaviour for some it is because they are just bad people taking advantage of others and committing crimes as any other religious person may. I would suggest that Political Islam has some very difficult problems unique from other religions.
Racism The Arab people have writings the Koran, the 6 Hadiths and the Sira and these writings regard all non Arab peoples to be Inferior.
The treatment of women. The Islamic writings give women no rights in Islamic countries and in those countries if a women is raped the women is then killed. The rapist gets off . We should ask ourselves the question is this what is happening in Europe? Men are not responsibe for rape.
Mohammad approved of rape of prisoners of war and the rape of children remember he married a 6 year old. Mohammad being the perfect example for Muslims to follow is believed by all Muslims just as Christians follow the example of Jesus . This is why we see child brides here is Australia being married to older men and also because Islam believes if they live in a western country they are in the house of non Islam and so at war. Could this be the reason muslims believe they can rape in western countries . Some Imams and even a female Imam have said western women should be raped by muslim immigrant men to be humiliated.
I could go on but this is just the tip of the iceberg.
