Hey Stanely, I agree completely that racism is still a problem in America, but I notice that you cite the killings of Treyvon Martin, and George Floyd as evidence of a culture of white supremacy. Yet, for every single well known case of a person of color killed by cops there has also been a white person killed in almost exaclty the same way. For instance, in 2016 Tony Timpa (a white man) was killed in almost the same exact way that George Floyd was killed. He begged for his life, and even cried out for mom, and the whole thing was even caught on camera. I reccomend this article for a more in depth look at what I'm talking about https://quillette.com/2020/06/11/racist-police-violence-reconsidered/. If you get a chance to read it I'd be curious to hear your thoughts.
