What would John F. Kennedy say about tolerance and communication in 2016?

We'll never know, of course, and I am loathe to put words in the mouths of former presidents.

But I have always been a fan of this quote attributed to him:

"The great enemy of the truth is very often not the lie, deliberate, contrived and dishonest, but the myth, persistent, persuasive and unrealistic."

So, when I presented last night at the Jordan Business Council's event to promote tolerance, I substituted 'truth' for 'tolerance' and came up with this:

"The great enemy of tolerance is very often not discrimination – blatant, malicious, brutal – but non-acceptance – insidious, habitual, passive."

I firmly believe that all the world's problems can be solved through improved communication, but as we know there are also many things working against this.

So, borrowing from Kennedy's line again, it seems to me that:

"The great enemy of communication is very often not its absence – silent, withheld, suppressed – but miscommunication – incomplete, ambiguous, vague."

What do you see as the great enemy in your field?
