Words are "actions."  The represent our thoughts and our values.  They are the "window" to our character.  I care very much about what people say and what they write. Both actions represent our presenting ourselves to others.  They also have important impacts on others.  If you tell a child he or she is "stupid" or "worthless" often enough, the child will believe it and it will impact his or her future.  If you advertise your disrespect for women as does Mr. Trump, you "model" those values for others who see you as a "leader."  If you promote racial prejudice, misogyny, xenophobia, classism and anti-intellectualism (as does Mr. Trump) with your words, you encourage those values in others.  

If a young man "grabs a girl by the $#%$" and is arrested for sexual assault, should "hey, President Trump said it's OK" be a solid defense?

You consistently trivialize such concerns as mine as "Politically Correct" and, therefore, meaningless and contemptable.  That's a weak defense for Mr. Trump
