Discussing measures that could or could not be effective is one thing in this thread, but posting cloak roomy memes is another entirely. There are plenty of threads for that stuff.
But since you mentioned children, I have noticed that @Brisketexan never responded to the fact that his assertion about guns being the number one cause of death for children being misinfomation. It's ok to admit that you were suckered in by an emotionally charged headline and didn't take the time to properly vet the claims. Ill even admit that I got the percentages I cited from a reddit thread and haven't checked them out for myself yet. We all, well most of us, have day jobs and families and can't spend every waking hour chasing down exactly what is and isn't fact, which is one of the big reasons why misinformation can be so dangerous. If I get some time, I'll try and confirm that those numbers are accurate, but between work, select soccer for the oldest, coaching three year old soccer for the middle, and trying to reign in the youngest who apparently just wants to watch the world burn, I've already got a pretty busy schedule.
