The truth is Democracy is a bitter pill. It's not all sunshine and rainbows. Like it or not it seems this group represents some of the Greek people and it's their right to elect these people. If you want to "do something" about the Golden Dawn, donate money or volunteer for an opposition party. You can't suppress opinions you find inconvenient or even offensive. Even in the US, there's tons of things that happen every single day that I'm completely outraged about, but I don't try and silence people I disagree with. Instead, I donate money and time to people who I feel will work to change these things.
