3.
IGB
Acronym for "It Gets Better" - a channel on YouTube where videos are posted for bullied gay and lesbian young people, encouraging them to hang on during their high school years because life gets better after that. Started by columnist Dan Savage specifically as a suicide prevention resource, after publicity surrounding several gay/lesbian young people who were lost to suicide in Autumn 2010.
I think Obama's support of gay and lesbians is genuine, not just playing politics. He even made a video for IGB and he didn't need to do that.
