The problem is that they project these ideas onto the entire male gender within free societies where they are in a minority.
And they influence the thinking of those non muslim males around them. or at least that is the way it is appearing to me.
In their effort to control my teenage sister before she ran away, it wasn't only my brothers muslims friends dragging her home if they caught her out, the non muslim boys who hang around with them, were also conscripted into the duty of controlling her, and having spoken to these guys, I know their mind has now leaned towards seeing good girls, as ones who stay at home wearing hijabs, and stay purer than the non muslim "slags" they like to view the world in.
I even got into a debate with my brothers british carribean friend, who was bemoaning how slutty girls dressed, and how they lacked modesty. All of this, because he spends far too much time with muslim males.
This attitude spreads and infects people, who let's face it, weren't entirely educated away from a way of thinking that wasn't so long ago, the way every male thought in this country anyway.
