So at first, there was outrage at United. Everyone was shocked at how the airline security personnel brutally assaulted Dr. Dao and just dragged him off of the plane.
Then "journalists" did what they do and some newspaper from Dr. Dao's home state decided it was relevant to point out that over TEN years ago, Dr. Dao was forced to stop practicing due to charges against him for sexual harassment of a former employee and prescription drug violations. After paying the penalty for his crimes, he was allowed to resume practice in 2015 and, thus far, seems to be on the straight and narrow.
The story wasn't relevant at all, had absolutely nothing to do with him being assaulted and dragged off of the plane, but, again, journalists will be journalists: they love to create controversy and dig up old issues.
After that newspaper broke the story, other stations and newspapers began including it in their stories, as though it was relevant. National news, when talking about the incident, didn't fail to mention the crimes committed by Dr. Dao in 2004/2005.
Then I noticed comments on social media beginning to change. Dr. Dao wasn't a victim anymore. He was belligerent and it was all Dr. Dao's fault for refusing to leave; he was a criminal, after all.
This is the best thing to happen for United. The narrative has been changed from outrage against United to questioning and blaming the victim, Dr. Dao, who, if you didn't know already, was a criminal and had his license revoked for several years.
