If anything, I would think that this attempted coup would teach us that there are issues far more important than guns. Issues we've been sorely neglecting. If we fought for education with the same fervor that guns are fought for, then there wouldn't have been nearly as much support for Trump and his lunacy. If we fought for freedom to choose our own content online, and fought against advertisers deciding what content we see, fomenting violence and partisanship because "engagement" is more important than anything else and it pays to show people content with the potential to radicalize them. If we fought to abolish the Electoral College, get rid of the two party system, abolish first-past-the-post voting, and other important election reforms... If we fought for campaign finance reform, taxing the rich, reforming healthcare....
If we fought for the things that actually made a difference this year, then it wouldn't have gotten to the point where anyone would even question if guns could have made a difference. Fighting for guns to protect our freedom in the age of the internet is like adding a room onto your house to store dried cow patties in case you need to burn them to keep warm in the winter. It's a really shitty backup plan, and it'd work a lot better to spend the time/money/effort on making sure the heater works, and maybe having a fireplace with a supply of wood. Spending a lot of effort on the worst way to solve problems doesn't make sense when it's taking effort away from much better solutions.
