I'm going to go ahead and call it, this whole thing was staged and he knew the guy that got arrested and was hoping it would turn into a "look all you have to do is talk them down" scenario. Why would he bring up that it's not illegal to brandish a knife only a gun?
Unloaded, locked in a pelican case, inside checked bag. Ammo has to be in factory boxes. It is illegal for them to visibly differentiate the bag from any normal checked bag (i.e. special handling tag), however they damn sure track the scanned tag closer, and get very snippy when your bag gets delayed and they cant give you an eta, and you explain that your next phone call will be to the FBI to report a stolen firearm moving across state lines.
The problem is peoples attention span, when it comes to boycotts. Dick's took a huge hit dropping guns, then opened Field and Stream when they realized guns make WAY more money in the midwest than golf clubs and athleisure wear, correctly gambling that people wouldn't connect the dots on who the owners are and simply would get excited about a new "gun/outdoor megastore" in the shopping mall. Then they doubled down and removed AR15s from F&S and started the losses all over again.
Pretty sure this is a reaction to the "bake the cake bigot" ruling not affirmative action. That being said, if they don't go broke from lack of sales, they will from the lawsuits, I can't think of a religion that condemns "Trump Supporters" specifically, which is the issue at the core of the cake ruling.
