There is no need to divide people into special interest groups to solve problems. The All Lives Matter slogan is inclusive, non-discriminatory, and the phrase “all lives” includes black lives.
The phrase “Black Lives Matter” implies that white people’s lives do not matter. The slogan is unnecessarily divisive. People of all races face difficulties and problems, not just black people. People who care about equality should care about white people as well.
“Black Lives Matter” is a racist slogan. Black lives matter amounts to a form of reverse discrimination. 
The Black Lives Matter slogan symbolizes hatred and division in the same way the Confederate flag is. The behavior of some Black Lives Matters protestors proves this. They are sowing discord, not bringing people together. Focusing on what divides people will not help to solve anything.
The supporters of the All Lives Matter Campaign are not racist; they just do not like divisive rhetoric. The phrase "All lives matter" includes black lives.
