If I had a business Facebook page, and someone put something on it that I felt was derogatory and untrue, I would delete as well.
There’s a difference between criticism and a derogatory remark. Something Rickenbacker and its minions never seem to grasp. It’s a “love everything we do or get lost” mindset. The word for that is “insular.”
Oh well. No good deed goes unpunished as the saying goes. Rickenbacker is what it is. And it’s not like anybody doesn’t know that already.
