There isn't much to discuss though. But people should still be free to express their views whichever side of the argument they land on.
My opinion wont be changed by anything here, but if if people who like flying stopped protesting it'd be seen as some kind of "victory" and would the silence would be used to prove how popular being grounded is.
Likewise, if the people for being grounded stopped speaking up no doubt that would be used as evidence that no-flying was unpopular.
