His ideas are sound, but times exist when such language is necessary. Imagine a job interview where someone was completely honest and did not make their faults appear to be good things. For example, I worked my last job for seven years. I received an interview with a new company and she said, "Well, it seems like they did not treat you very well." I replied, "Regardless of how they treated me, they taught me everything I know and for that, I will always be grateful to them." If I had replied fully truthfully, as opposed to bullshitting just a little bit, the poor woman would have received a barrage of misdoings and wrongs that I was the brunt of, and I would not be employed.
