Alright, so I don’t necessarily agree with Laci in that culture is an illness, but aside from that I believe anyone involved in American culture should see this issue clearly. This is not about guns or knives or weapons, but about the psychology of a culture. Take a look at Laci’s thoughts (forewarning: this may not be entirely appropriate for young audiences, but it must be addressed one way or another).
Also, I would recommend taking a look at her note about blaming mentally ill people here. You can read more statistics similar to the distressing ones Laci found at Mother Jones (as posted on Upworthy).
This is a pervasive problem. It’s past time to put the politics aside and figure out what we can do about it.
