Yes, all lives do matter, but given the current issues in our world facing the black community (it's all over the news and the internet, if you don't know what I'm talking about, just open your local search engine). The term "black lives matter" has been a long lived one, it's a quote that is being used to show the other nationalities in the world that they are as much part of the human race as the rest of us. Slavery ended 70+ years ago, but segregation still exists, all you need are the tools to understand and to see it and the education to help fix it.. and using "all lives matter" is not how you're going to accomplish this.
The black community of America, and in other areas of the world too, lack the privileges of some other more "favorable" races, ie western/white people. It is a proven fact that they are targeted more in hate crimes, chosen less for jobs, and have to work much harder for college and careers than some others do. Yes not all people experience privileged or racism, but too many of us still do. See this video for more information: https://www.youtube.com/watch?v=FBQx8FmOT_0
In this image you can see a chicken, it's holding a water hose and is watering the "all lives matter" house, because it believes in "equality". However, in coining this term and ignoring the "black lives matter" house, it is refusing to show understanding to the fact that.. yes, these houses are the same, but the "black lives matter" house is on fire and needs help a little more than the "all lives matter house", does it not? So what I am trying to say is... if you're of the belief that the house that is stable and secure needs more attention that the one that is currently burning, that your ignorance refuses to see that there is a problem here and that justice and equality isn't what we thought it was.. you are part of the problem.
See this for a more in depth visage of what I am trying to explain:

If for some reason you disagree with my statement, if you still believe that "all lives matter" and privilege is just a myth used by the supremacists in our world.. please comment below, I'd love to hear your thoughts. :)
@ CS staff, if you delete or edit this, kindly make your own post on the front page and show us that you guys actually care!! Because, to many of us, it appears you're refusing to acknowledge this and are allowing the racist, homophobic, and supremacists to continue to suppress and abuse their fellow humans. Every single other site in existence has acknowledged this, flight rising, lioden, dapplevolk.. but not you. Don't be part of the problem, be part of the solution.
