[ Politics ] Open Question : Questions for you “all lives matter” people?

When Vegas was shot, why did people say “Vegas strong” instead of “All cities strong”? After the Boston Marathon Bombing, why did people say “Boston strong” instead of “All cities strong”? Why is it called “Breast cancer awareness month” instead of just “Cancer awareness month”? Don’t all cancers matter? When a house is on fire, why do the firetrucks only spray water at that house instead of all the other houses? Don’t all houses matter? Don’t you guys see that it’s stupid for you to say that all lives matter? We say black lives matter because black lives are the ones being attacked. Cops already know white lives and other lives matter, but we need to focus on black lives because they’re the ones being affected right now!
