You need to read Felder's book & then you will know what 'bitter & irate' is. There were two people in the argument.
I honestly don't want to sound as if I instantly have to rush to Glenn's defence when I obviously haven't seen it. But he isn't perfect. He is human & he had/has as much right to be angry about what happened as anybody else did. As I said, I prefer honesty to sugar coating.
