If that post is directed at me, I am confusing nothing. But you sure seem to be confused. Where are you getting this nonsense about "active shooters"? That has nothing to do with any of my posts, or the posts of those who have shown themselves to be liars or uh, something even less charitable, like math professors.You're all confusing "mass shooting" with "active shooter" situations.
A mass shooting is just that: the shooting of a large number of people in one event. They happen every day. The vast majority of them are committed by criminals, doing criminal things, for criminal reasons, against other criminals.
An "active shooter" situation is when someone enters a place filled with soft targets to kill as many as possible. They are fairly rare. Here in Canada almost unheard of... We could likely name every one that's happened here in our life time with only a little thought.
The problem is the media (and many of us here) cite statistics on one when talking about the other. Most active shooters are white males. So we talk about active shooters, present demographics on them... Then we turn to mass shooters for the numbers to make white people look disproportionately violent. For example when you hear 'school shooting' you think Columbine style, right? Then the media tells you how there are multiple school shootings in the US everyday and you think (and so do your kids) "my God everyday!" But they neglect to mention that most of those are two people who know each other in a conflict, usually relating to gangs and drugs. Does that make it okay? No. But it's very different then... "All of our kids live in fear of being shot at school." Or David Hogg telling us that his generation just accepts the reality that they might get shot at school.
It's poor reporting and poor statistics. Each of those 2 categories have different reasonings and victimologies. They can't be discussed together.
As to why active shooters are mostly white, there's a lot of reasons. They tend to come from suburban or semi-rural environments, be middle to upper class.... Many factors that lead to an over-ambulance of white males.
My theory is that violent people from other races have outlets for violence even if they are raised in suburbia far from violence... A violent sociopathic upper class black kid can join a gang (his entry point is his race), a violent sociopathic poor white kid can join a gang (his entry point is his neighborhood and economic status). A violent, sociopathic upper class white kid has no entry point into a world of violence so has to make his own. This isn't to excuse the behavior. But there are reasons for everything, even if they don't make sense to those of us with normal functioning brains.
And of course these aren't absolutes. There's exceptions to statistical norms.
