tbh i dont know if its even just a general white male problem... its white men in the US (specifically nationalists) specifically... as michael moore pointed out in bowling for columbine there are a TON of white men with violence in somewhere like canada, but the violence statistics are much lower than in america.. obviously there are examples of other countries having intense violent hate crimes (EDL, the Quebec mosque shooting), but the intense amount is much less strong than it is in the US, specifically because of a specific culture of fear and facism and racism
Isn't it because in America people have easy access to guns?
