Every discrimination case involves some amount of he said/she said. Most acts of discrimination occur behind closed doors. So, the testimony will be all about a swearing match. But, that does not mean the two stories cannot be confirmed or denied. In a discrimination case, we would want to know, for example, the circumstances behind a demotion or a firing. Does the story make sense? Do the surrounding details support or undermine the main story line?
It is the same with Judge Brett Kavanaugh and Dr. Christine Blasey Ford. The fact that no witness appears able or competent to confirm or deny their respective stories does not mean either story is false. The details become more important in such situations. Dr. Blasey Ford remembers very few details, other than the actual assault. She does recalls, however, that she saw Mark Judge at a nearby Safeway grocery store weeks after the incident. When we look at the book written by Mark Judge, we do indeed see that he worked at a Safeway in the Summer of 1982. Mark Judge wrote a book about his recovery from alcohol abuse. It goes into great detail about his excessive drinking in high school. So, again, Dr. Blasey Ford’s story is confirmed in another respect, that a young Brett Kavanaugh drank a lot. And, in another important detail, Mark Judge mentions that he and his friend, “Bart O’Kavanaugh” partied hard in high school. See Rolling Stone news report here. “Bart” appears several times in Mark Judge’s book.
That is how a discrimination story is confirmed or denied, on the edges, around the periphery. It is circumstantial proof. But, sometimes circumstantial proof is more trustworthy than someone’s hazy memory.
