It's the least we can do. I understand, "wear X color for Y cause" campaigns are WAY overdone in our society. But come on. Anyone who supports the Iranians marching for freedom while wearing a Red Sox cap, a Lakers jersey, or a Nike logo cannot even start to argue with this. Really. What's more important here?
Just look at Al Rodgers' highly recommended diary. Showing the color is obviously a huge point of solidarity with these people, and I think most of us are with them.
So...if you support the people peacefully fighting for freedom in Iran, WEAR GREEN.
