Anyone who thinks making guns illegal in the US would be a good thing is clueless to the much of the country.
edit: also how many people int he military do you know, or retired military people? I can't think of a single one I know that didn't grow up with guns, or has them now in their house. Also the vast majority of those I know are form rural areas, not the big cities. You know the areas that are hugely against these laws. So I wouldn't count on the military members being supporters of gun laws. if they were forced to confiscate guns from Americans, they would be confiscating them from their family/friends.
Keep in mind that the NFL didn't see a ratings drop because of ridiculous things like the right protesting them and making a difference. The ratings are dropping thanks to the riseof streaming, awful officiating, and because it seems like the Patriots will never go away.
The extreme right wing nutcases are just trying to take credit. Delta and US Airlines will be fine.
