Answer and Explanation:
Wingfield scolds Smith and says it is not fair to make accusations against those who have always been on your side, the "your betters". Wingfield cannot accept this type of behavior and accusation, he finds it revolting and it reached the peak of his impatience.
He becomes possessed of rage when his lineage is insulted and this makes him understand how much he values blood ties and how faithful he is to those who are connected to him in some way.
