You may have a few westernized friends but tell me do they go to Mosque on Fridays and do they pray five times a day ?
The Iman at some Westernized Mosques preach a benign Islam but that is changing.Most Mosques receive heavy funding from Saudi Arabia and with that funding eventually comes Wahabbi Islam,a much more militant version.
" It would be a mistake and unethical to criticize all of Islam on the basis of doctrines particular to Wahhabi Muslims. Modern Islamic extremism and terrorism simply cannot be explained or understood without looking at the history and influence of Wahhabi Islam. This means that it's important from an ethical and an academic perspective to understand what Wahhabi Islam teaches, what's so dangerous about it, and why those teachings differ from other branches of Islam."
" Even though Wahhabism is a minority position overall in the Muslim world, it has nevertheless been influential for other extremist movements throughout the Middle East. .....This can be seen with a couple of factors, first of which is al-Wahhab’s use of the term jahiliyya to vilify a society which he does not consider pure enough, whether they call themselves Muslim or not. Even today, Islamists use the term when referring to the West and at times even to their own societies. ....With it, they can justify overthrowing what many might regard as an Islamic state by essentially denying that it is truly Islamic at all."
