If you don't offer solutions and how you'd implement them in US, why bother? You keep repeating yourself over and over. Just because there are like-minded individuals who believe gun violence sucks, doesn't mean they have any realistic way to curb it.
If you have a solution, present it. Let's talk about it. Let's discuss its merits, and its flaws. You aren't engaging in intelligent discourse, you're proselytizing. You don't want to formulate an argument or change someone's mind with a rational, logical argument, rather convert folks to scream at the top of their lungs that something must be done, even if no one knows what that something is. You want mindless drones who have no thoughts other than non-productive outrage. You are a contributor to some of the biggest problems in the West today.
