Who's blaming all Muslims. I'm blaming the ideology. Why is it wrong to say Islam is f**ked up?
Maybe in the past you could control what Muslims in your community learnt from the Quran but those days are long gone with the birth of the internet.
Until islam as a whole declines there will always be extremists. This will go on for centuries. People can bury their head in the sand if they want but this is not going to go away any time soon.
