Motiviation for Facebook political postings uncovered back in 1917

Lawrence in Arabia quotes a letter from Aaron Aaronsohn (“Not to be confused with Aaron A. Aaronson, a fictional character in the Simpsons episode Sideshow Bob Roberts.”) to his brother, regarding an upcoming meeting with some fellow Zionists:

I told him that I was not going to London to quarrel, only to tell them their mistakes and to show them the way to do things properly.

I think this summarizes the politically-oriented posts that show up in my Facebook feed!
