Oh, thanks.
Personally, I think the joke is the idea of a "moderate" plan to limit my most important God-given rights.
"Grassley is considering five main points: addressing mental health challenges; reining in gun trafficking; preventing school violence and ensuring student safety; protecting veterans from false mental health accusations (e.g. of Post-Traumatic Stress Disorder); and improving enforcement of existing laws regarding state information-sharing for the background check database."
I fail to see how any of those things limit anyone's God-given rights.
