If you are against institutional racism, then stop giving institutions the power to perpetuate it. In one breath you say black people need free speech and to have their voices heard. Then the next thing you say is that institutions should be given the power to censor and silence anyone who has the wrong opinion. Right now you feel as if the culture is on your side and your opinions are the right ones, so you won't be affected by such censorship. One day you will find out harshly that culture changes, and your opinions now will be the wrong ones.
