Why would “Christianity” stop people from behaving like idiots? I could ask you a similar question: Why doesn’t Islam stop people like Choudry (who is, in your words, “a serious nutjob”) from advocating Shari’a law in non-Islamic countries? Why doesn’t Islam stop Osama Bin Ladin and his terror franchise from murdering innocent people of all religions? Why doesn’t Islam stop people from being violent and stoning to death 13 year old rape victims? Why doesn’t Islam stop the disenfranchisement and disempowerment of women that we see in countries where Muslims are the majority? Why doesn’t Islam stop Muslims from tearing down, torching, and otherwise defacing other peoples’ places of worship, as they have done to Christian churches and Buddhist temples across the East, and in certain places in Africa? Why didn’t Islam stop the Taliban from blowing up the Buddhas of Bamiyan? Why didn’t Islam stop Muslims from murdering Shahbaz Bhatti on Wednesday? Why didn’t Islam stop the horrible civil wars in Muslim-majority (nearly 100%) countries like Somalia and Afghanistan? Why didn’t Islam stop the killings in Egypt these past two Christmases, and the continued intimidation and brutalization of the native Egyptians at the hands of the sickos in the majority religion? Why doesn’t Islam stop the vicious genocide that is being inflicted on the Christians of Assyria by Muslim death squads RIGHT NOW? Why, why, why, why, why?
Perhaps a person’s religion cannot stop them from doing evil if they are convinced that whatever they are doing in the name of their religion is justified and good? Islam has no shortage of examples of this, both in the East and in the West. One-sided indignation rings hollow.
