If a point was made by this shooting, other than demonstrating the instability of the shooter, my toxic partisanship must be blinding me to that as well.  

I see no organization taking credit, no one supporting either the shooter or a cause, no point made whatsoever, except for a PM who apparently spotted the opportunity for a sudden rush to judgement to erase all memory of his ill-timed root cause comment in 2013. 

Most of us know enough to steer clear of bigoted connotations without putting on a complete blindfold.  Hopefully, before too long, we'll have a PM who trusts us with that capacity for nuance.
