you're missing the point, dum dum.
the bigger issue is figuring out what causes such violence outbursts.
but you only care if it's white boy with a gun doing bad things.
you give other people and other weapons a free pass, and refuse to look at the bigger issues.
the bigger issue is deep state dividing the nation on behalf of china with identity politics.
you're their stooge.
That is like saying debating the cause of the American Civil War is missing the point; we should look for the common causes in all civil wars, or the cause of all wars period. Mass shootings are a distinct phenomenon. If the AR 15 is a particular culprit, which it seems to be, and the shooters are of a particular type, as they most often seem to be, those similarities deserve to be identified and discussed. Not only the "violence" behind the "outbursts" is involved. In the case of mass shootings the common weapon of choice in the violence is involved as well. Your approach is one of avoidance. Whether you're intelligent or un-indoctrinated enough to see that is in doubt.
