I believe it is a distraction tactic. I, personally, focus on many topics at once so it's not like talking about Seth Rich distracts me from any of the other subjects, but I fear that others don't have the same ability. You know the kind...the kind that just follows what the crowd is talking about. There are many people behind the scenes that are just ignoring the sensationalizing and getting work done.

Edit: Also, op, this should go in /v/pizzagatewhatever
