Why can't New Labour just admit it has messed up big time?

Their pathetic refrains such as,"We are still learning,' and 'We only did as they told us,' are empty, shallow admissions to their lies. Just as Hazel's (Question Time) responses were false smiles personifying blind following bunker mentality. Her bloody minded stubberness typifies the rampant ignorance which allows the creation of an Idiocracy. Such opinions we have come to expect from a woman of such unenlightened stature..
