That's because you are clueless and refuse to understand the truth.

There was one (1) mass shooting in 2015 that involved a white male.  The other three (3) mass shootings, as there were only four (4) mass shootings in 2015, were perpetrated by African or middle eastern men and women.

Only a legitimate racist would write such an ignorantly hateful comment regarding white males.  

Time to turn off Facebook and enter the real world.
