Do African Americans use racism as an excuse or permanent blame

Racism has been an issue since the beginning of time or has it? Some say racism is an excuse, some say forgive yet, never forget. Some say, enough already and move on... Shouldn't all races be held accountable for slavery? And, shouldn't we all be accounable for racisms survival? One would think we've come so far still, we still have so far to go. Are we doing our due diligence to create change. We can not in one sense elect a biracial President and somehow decide 1600 Pennsylvania Avenue via Google is now considered "Nigger House" by the definition of nigger, it's ineffective and frankly niggerly. It's not what your called, it's what you answer too.
