This appears to be a step in the right direction for Russia. Putin knows that world opinion about homosexuality is quickly changing, and if Russia doesn't change as well, it will be left behind. This may be an attempt to make amends with those who were offended by the new legislation and an effort to salvage the situation before it can have negative effects on the Sochi Olympic Games.
This statement is so relevant now that we are in the middle of the Sochi Olympic Games. Russia continues to have highly discriminatory laws against homosexuality, which has been a huge controversy in these games. Putin may have allowed gays to come to the Olympic Games, but that does't even begin to help the homosexual citizens of Russia. This video is also pretty relevant- http://www.youtube.com/watch?v=n4CEaoNADiY.
Bach's comment is something all nations need to remember and will continue to be reminded in preparation for the World Cup and the Summer Olympics in Brazil as controversial topics arise. Although many do not believe that Putin will change his or Russian people's opinions, his views have caused poor public opinion of the Sochi games. Because of his viewpoints, Putin has made many enemies. As the games develop, it should be interesting to see how the Russia's government and public affairs deals with the negative press.
