How do you ever get someone to change their actions? You persuade them to do so. In the case of public officials engaging in a systematic cover up of child rapes, I would encourage them to consider whether their fear of being called "racist" and "Islamophobic" morally justifies them engaging in such a cover up.
Of course, I am relatively powerless, but the problem is that even those who do have the potential to change attitudes are silenced as well.
I think I would be more kindly disposed to these moslem chaps if they desisted from wearing their pyjamas during the daytime. Difficult to trust a chap that spends the whole day in his nightwear.
Furthermore my wife says that men wearing sandals all the time usually have no intention of doing any work.
