In my opinion 'political correctness' and tolerance are underrated values.
Those who do, I suggest that you go on to any christard forum and, politely tell them that you are there to discuss religion and that you are an atheist. You will then see what extremism is all about. Then, after they have rounded on you, you'll be banned for life. Not just on their forum, on all christard forums because they will pass on your IP address to every christard form from here to wazoo and back.
This is not true.
