This shit is happening all over the world, it seems. They just caught a "young white male" in Las Vegas, Nevada, who was planning attacks on a synagogue and an LGBT bar. I guess this means that we all have to watch "young white males" closely, just for the rest of us people to be safe.
your racism is showing.
as for your concern: how closely do they monitor islamic terrorism? or BLM terrorism? strange that after all the pushing of white males against the wall, all the hatred displayed by the looney left against them (you sexist, racist pigs you),it should happen, that some of them run amok instead of killing themselves (after all,suicide among white men has risen to crisis levels these past years)....so, we just do it like the looney left and their pet ideology : we declare each and every single one "mentally disturbed"...can't do anything about that, right?
