Deserving to be heard. And inciting a war which has the potential to hurt many innocents are very different people. This type of rally is more dangerous than yours mon amis. You mostly put yourself in danger, in a place where you knew which way to run to avoid the guard.
The Grounders are at an advantage here. And if they take this personally, it is likely not to end well. And there is no guarantee, considering some of the things I have heard from the Skaikru that they would only hurt the militant among us.
