If extreme negative emotions come through in persuasive writing then it will be ignored or marginalized by very the audience for which it is directed.—Glen Mella, former president of Control4, May 21, 2015
I asked Dr. Mel Luthy to rewrite Glen’s quote and here’s what he sent me:
If your persuasive writing is too emotional, it may lose credibility with those for whom it is intended.
A word of caution: If your persuasive writing is too emotional, it may defeat your purpose and
alienate your audience.
Discretion is the better part of valor.—Shakespeare
