//No. The people who criticize Islam have spent some time educating themselves about it.
The people that defend it do so because their newsagent, barber, etc, is a Muslim and he's a nice man. Ie, they know nothing.//
There are also those who criticise Islam who simply read Briebart and the Daily Mail and don't have the capacity for original thought.
And likewise, there are those who have grown up with, gone to school with and worked with Muslims, and can see that they are a spectrum of people. Some awful, some boring, some kind, some lazy, clever and some that you would you would avoid like the plague.
I honestly think that it's better to start separating Islam from Muslim, otherwise we can get into that mindset that they are one homogenous group.
