It's really amazing, "said Galetskaya, which brought the actress girlfriend Kelly Pan Am Garner on his date. "My parents were very political and did a lot of protesters in Chicago and Detroit and raised me to believe that the disagreement is not only your right but your duty when you are passionate about something.
