Let’s take something like Tibet or Xinjiang or Crimea, etc. All have good grounding for people to see where things might be wrong. I still don’t think that discussion should happen in the workplace agitating management to be active and organizing coworkers into friends and foes. If you have a political interest in that thing do it outside of work —it may involve like minded coworkers but don’t bring this to work. Exception is Union organizing, that necessarily involves workers and management.
