While it'd be ridiculous to paint every Muslim in the same brush and say Islam hates us or something stupid, there are obviously the unhinged and small sections of extremists that would use the faith as a guise for their own violent nature, no different to how every self-serving religious person twist the faith to fit their own prejudice throughout history
Just on the bolded bit, I think the sad reality is that minority isn't that minor, especially when we look at the stats:
Pew Research (2010):
84% of Egyptian Muslims support the death penalty for leaving Islam
86% of Jordanian Muslims support the death penalty for leaving Islam
30% of Indonesian Muslims support the death penalty for leaving Islam
76% of Pakistanis support death the penalty for leaving Islam
51% of Nigerian Muslims support the death penalty for leaving Islam

2013:
Only 57% of Muslims worldwide disapprove of al-Qaeda.
Only 51% disapprove of the Taliban.

Pew Global (2006)
68% of Palestinian Muslims say suicide attacks against civilians in defense of Islam are justified.
43% of Nigerian Muslims say suicide attacks against civilians in defense of Islam are justified.
38% of Lebanese Muslims say suicide attacks against civilians in defense of Islam are justified.
15% of Egyptian Muslims say suicide attacks against civilians in defense of Islam are justified.
Now you might think ok those aren't westernised Muslims so it's not surprising - but the numbers in the west are alarmingly high too.
Pew Research (2007):
26% of younger Muslims in America believe suicide bombings are justified.
35% of young Muslims in Britain believe suicide bombings are justified (24% overall).
42% of young Muslims in France believe suicide bombings are justified (35% overall).
22% of young Muslims in Germany believe suicide bombings are justified (13% overall).
29% of young Muslims in Spain believe suicide bombings are justified (25% overall).

When you see those numbers it's no surprising you get regular attacks in Europe like we now see.
