Yes. Female is 3.6% according to article I linked above, so some may consider male "nearly all". White is 57% according to the statistics link I posted above, so white is inaccurate even with "nearly all". Thus, "nearly all" "male and white" would be wrong and misleading. The more important question would be, does either of those help identify potential risks? So you should turn the statistics around: What percentage of males become mass shooters? (0%) What percentage of whites become mass shooters? (0%) So, yes, males and whites "tend not to go on murder rampages". Not particularly helpful. Of course, the same can probably also be said about their other "things in common", but maybe we can identify something that will help.
