Autism is a common link with these shooters. Adam Lanza was autistic, killed 26 people including his mom. He targeted kindergarten kids, the wall mart shooter is on the spectrum, as is Toronto van killer Alek Minnasian. Having worked with high functioning autistic people, they are for the most part good people but I wouldn't want a gun in their hands. Most are socially awkward, often isolated, and make very poor decisions under stress. They SNAP. I agree with many of the things Fortress and Matt post but not to the same degree. Matt is one of the most dangerous people on Getbig. Always minimizing and blaming others. I would not be surprised if he harmed others. This guy is not stable. 
I'd start addressing the fact that 70% of all murders in the USA are committed by Blacks and Hispanics in the USA, and the fact that out of 112 gang rapes of females in Sweden in 2017 [median age of victim = 15] than worrying about the upcoming White response to this stuff, which will indeed be many, many times more violent.
Look up Jessica Yaniv on YouTube. Biological males are now allowed to sue female Brazilian wax specialists for refusing to handle their genitals.
It's only a matter of time before much more significant White backlash to this stuff takes place
There are a million interracial crimes of violence in the USA each year. Whites comprise 90% of the victims of those crimes.
This backlash isn't happening for no reason.
I wouldn't be worried about me.
But if you think this is bad now, you ain't seen nothing yet.
