Deep in American culture, we have severe problems with rape, racism, and guns. We spend so much time focusing on the individual cases, pretending they are fluke events(that somehow keep consistently happening) instead of working on the root causes that make these issues almost institutions.
Rape culture isn't just about rape. It's about the constant pressure we put on women, and responsibility we don't hold men to. It's about the context in which we talk about and treat sexually open women. The idea that a woman was "asking for it" is absurd; the idea that a man "just can't control himself" should be infuriating. This is rooted all the way down to the idea that men can't have platonic female friends without wanting to sleep with them.
Racism isn't just social acceptance(slowly and surely) and abating police violence(hopefully). Racism is about systematic and institutionalized disadvantages that limit opportunities. Racism is the child of hatred and ignorance kept alive in cultures by naming itself "tradition" or "the way things are".
We have a problem with gun violence. Yes, the majority of Americans that own guns are reasonable(with their guns) and responsible. That doesn't mean we can ignore the severe consequences from the minority who abuse their access to weapons. 'But nothing can be done, criminals and crazy people will get weapons anyways' -except in ever other civilized country where this doesn't happen. How many friends, family members and children need to be murdered before we do something? Most recently, the murder of 9 black members in a church(which was also the assassination of a U.S government official BTW) is at the forefront of tragedies that will get ignored.
There is a lack of accountability, an illusion of no choice, and a severe dedication to ignorance undercutting our ability to grow as a society. At some point, if we want change, we're going to have address all three.
