While I agree that a concert to let the Palestinians know that the world cares. However, is this the same reason the organisers have in mind? If their reason is to cause a steer which would instigate further uproar, then it's a bad idea.
They are probably doing this to spread more awareness and most likely they will be giving a percentage of the profit from the concert to give aid to Palestinians. Causing a steer is inevitable. It is a political issue that has been going on for months and yet no one seems to listen. Everyone should be more aggressive and assertive when it comes to expressing our stance.
