Did you read this article:  http://fivethirtyeight.com/features/education-not-income-predicted-who-would-vote-for-trump/?  It suggests a different analysis of Trump voters.
I agree with you about all of the white Catholics (60%) and white Evangelicals (80%) who voted for Trump.  The nuns to whom you refer do fit into this category.  They absolutely ought to be held accountable.  
It pains me that those religious who favor women priests are refusing to come out and take a position publicly.  I believe that if they would all stand together, there would be nothing to lose -- especially now.
