Has politeness affected our ability to tell our truth?

In this podcast we look at how the notion of 'being polite' has impacted our ability to bring our truth and discernment with the truth in what we see around us.   
In many instances we have come to see politeness as a sign of 'many things good' including respect, kindness, duty. 
However is that really true? 
And will politeness help us to determine what is really happening within us and in others? Will it help us to connect and sense what is beneficial to ourselves or our relationships with others?
