A relevant quote:
“Events in Russia are solely to do with domestic politics. In individual cases sportsmen have been affected. If a certain anti-Russian press feels called upon to deliver these domestic Russian matters on to the Olympic stage, then this is extraordinarily regrettable and shows their unfriendly attitude toward Russia in the worst possible light.” – Dr. Karl Ritter von Halt, the president of the Committee for the Organization of the 2013 Winter Games.
This has all happened before. It will happen again. So say we all.
An American athlete, in Russia for the World Championships, just dedicated a medal to his gay and lesbian friends. That might be the best approach, rather than a boycott.
