I’d say the argument is pretty much done, anyway - since now apparently there were also 4 armed deputies (last responders) outside hiding behind vehicles. But of course as my father in law says (a gun enthusiast) apparently there are 10,000 incidents per year in which guns have saved people. I suppose it comes from that telephone survey where they asked 1500 people how many times they were protected by having a gun. Gun rights activists would of course say they did, probably every time they walked around carrying one.
The key thing is now that the kids are vocal, to stay on track and continue with the targeting and the boycott, if corporations have the same rights as humans, and free speech=money as citizen’s united (both BS) let them feel it where it hurts. Recall that after the Vegas shooting something was going to be done about bump stocks - forget it, if anything they passed laws relaxing regulations.
Consider how powerful the gun lobby has become, with all the Grade A etc rating for every politican
(See Marion Hammer in the recent New Yorker) the other side needs to get even more activist.
Corporations may find there is no middle ground such as Delta Airlines, whose tax breaks are now threatened by the Lt. Gov of Georgia. I’m sure he is also aware that thanks to the Delta Air HQ in Georgia they are the largest employer in the state. Meaning that other states would be happy to attract them. While for instance Amazon may think twice about Savannah.
It is interesting to note that much of the NRA activism is relatively recent since the late 60s More Perfect the Gun Show
