Answer:
In my opinion, all lives matter is saying that at the moment, everyone's lives matter, and yes, everyone life is unique and important BUT is everyone in need of help right now? Is anyone in fear of dying every time they step out? (i mean ya cause of corona but pretend corona isn't here).
Lets say in your neighborhood, a house is burning. Your first thought is to call the fire department for that specific house right? All lives matter would mean that a fire truck would come and put water on every house in your neighborhood, even if they don't need it.
I hope this answers your question :)
ok but the thing is why does everyone keep saying acab, kam, kaw, alm, blm. Like we're all human. Some of us are bad some of us are good. We shouldn't change our opinion on something just because people in that category made a mistake. For example, we generally know that males frequently assault females and vise versa, BUT we don't judge an entire gender based off some peoples acts (i know it's a lot but I'm just going to use the word some). This is the same with cops and other people. Also i don't think we should burn the American flag. A lot of people died for it and although, yes, the flag represents the trash country America is currently, but it also represents the history of the very land we stand on today.
