Its a response not an attempt to silence. We are pointing out that all people can face hardships and experience police brutality. There for all lives matter. Black people are not the only ones to experience police brutality. Police are not more likely to kill black people when you adjust for crime stats.
If we are trying to get rid of racism, shouldn't we start by not making a big deal about one particular race? Everywhere people make a big deal about blacks being badly treated while simultaneously executing reverse-racism on whites, etc etc. Shouldn't we all just decide to be equal? Every person walking down the street smiles and says hello to every other person they meet, no matter what colour. Tbt, we are all part of the same race, which is called the human race. Somehow we decided that colour was enough to set us apart, and we haven't been the same since. AllLivesMatter is a reasonable saying and I like it better than BlackLivesMatter, because BlackLivesMatter is forgetting about everyone else. No one deserves special treatment, if we really are equal.
