When we talk of extremist religious fanatics we usually refer to say, Christians who blow up other Christians with nail bombs or say, Christians who go on rampages gratuitously slaughtering Muslims in African villages almost on a daily bases or even just, say, Christians sodomizing young alter boys. And just not to show any bias, I suppose in recent times we have seen extremist Islamists blowing up anyone, including themselves.
But, what about the beliefs that religions prescribe? For example, all Christian denominations openly prescribe belief in vilifying minority groups, elitism and hatred against virtually anybody else who doesn't believe what they do? Then, of course, there is the old fashioned sexism and general anti-social behavior that all religious groups have been infamous for.
So, is it not fair to say that anyone who holds a religious belief is extreme by normal, secular, civilised societal standards?
