Sadly tolerance in this age is defined by an ever changing system of beliefs that is popular today and if you disagree with the current popular notion you are labelled as intolerant.  It is self-contradictory as why is your system of beliefs better than someone who believes differently than you? Why are you not considered the intolerant person? 

One cannot even discuss what is right and wrong without appealing to a moral law and a moral law requires a moral law giver. The million dollar question is who is the moral law giver? In the communist era it was the government and we can see the destructive force that took the lives of 10’s of millions of people. In the post-modernist world view we have today, each society figures out their moral law and calls all other societies that disagree with it intolerant, bigoted, simple and unsophisticated.

The 20th century has been the bloodiest with more lives lost than all other centuries combined most of which had nothing to do with religion.
