You must live in a very sheltered world, indeed, Sr. Maureen, if you do not know any Trump voters.  Most of us meet them at the Post Office, at work, in the grocery store.
One thing that they all have in common is that they do not believe that homophobia or racism, or assault of women are unacceptable.  If they did, they would not have voted for the man.    
I tried to speak with some Trump voters before the election, but was told that Hillary is a liar, baby-killer, national security threat, etc.  They insisted that their statements were fact, not opinion, and there was no way to reason.
Talking with racists about racism is usually difficult, because many make racist statements and then insist that what they said was not racist.  
I do agree that if the Republican candidates were to stop scapegoating immigrants and non-whites for the plight of the middle class, we would all be better off.
