Gun Control Reform Activism

That is 9% that almost certainly votes every election, and harasses (or worse) any politician who even talks about doing anything about this.

To compare, African Americans are 13% of the population and has 62% turnout in 2020. The gun nuts are a voting bloc of essentially equivalent size.

Blaming the gun lobby is putting the cart before the horse, the gun lobby would be powerless without the millions of hardcore gun nuts backing them. The NRA is a broken dysfunctional shell it's it's former self, fundraising down by half and losing members. Yet the gun lobby is still strong because the zealots are just shifting to other groups - most of which are even more extreme and insane.

Breaking the gun lobby can only be done by withering their support. The only way to do that is cultural change, which is not a fast process. The start would be to push to remove guns from games and media, and focus on ways of discouraging first time gun purchases.
