Esquire reported in Ft. Lauderdale Emma Gonzalez exclaimed to a cheering crowd, “...'shame on you' directed towards all politicians who take NRA money." They are serious and have made several exclamations that they hope to make this the "last" school massacre. You can see the full transcript of Gonzalez's Ft. Lauderdale speech on CNN. The older groups failed to get anything done, no doubt because many of them own guns and are members of the NRA. The younger group, 30s to 40s, have some advocates for gun control but apparently not willing to fully get behind the program.
But when it happens in your school, and you are a community like Parkland, Fla, you do something, and that's what is happening. Maybe it takes a group of late teens like these students who are not yet a part of the American gun culture that has literally ruined this country since the resurrection of the 2nd Amendment, and they simply don't give a damn about guns. I don't either, never have, and hope like hell they succeed.
