Wow, thanks for the video actually. For a long time I felt he was complete jerk but I felt it was maybe biased propaganda. The mere fact he couldn't answer a basic question and explain for all those who don't know, but rather stormed out like a 4 year old child, only proves what I felt about him prior.
Your comment is a great example of someone deciding on a conclusion first, then backfilling a justification using minimal evidence—in this case, a single data point—to validate an existing suspicion or bias. With that standard, you can make virtually any public or semi-public figure look bad if you’re willing to cherry-pick a small enough slice of information.
