Racism long ago shaped the structure of American society. It existed in a systematic form. People would wrongly justify acts like George Floyd's shooting and get away with it. Today racism still exists, but in a covert form, in which we rush to deny its existence yet witness its effects on a daily basis.
As much as you try to negate it, humanity is vanishing and we're not speaking up as we should be doing. Floyd's killing will sadly make the headlines for a few more days before the world forgets his name along with the innocent others mercilessly stripped of their rights.
Societal power is strong. Nations built on a representative democracy like the UK and US are world leading for a reason, most legislation is passed if the public endorses it. Racism if not overthrown, can be diminished, if we show continual will and ambition, and unify our voices against this hatred just as the world has with the unlawful murder of George Floyd.
