I remember the day I began to hate Ronald Reagan.  It was the day I realized how much he had contributed to the dehumanization of other Americans by promoting policies that increased homelessness.  It was the day I came up the escalator from the DC Metro into the middle of the Mall and saw multiple homeless men and women huddled over grates for warmth.  I was a visitor in a city I had lived in 6 years before.  WhileI lived there most people on the mall were tourists.  I left DC when Reagan was elected. It was a shock to see how things had changed during his presidency.  

So I can relate to your feelings of anger that are intricately connected to your affection for a city in which you once lived.
