When the evil bigots upholding the racist institution also happen to be moderate BIPOC - then the question should be asked.... who is being racist here? You? Them? Everyone? In answer to the question you've posited in your subheading... I do think America is a racist country, but I don't think fanning the flames of racial prejudice will make it a less racist place or any safer for black or brown people. When you're starting to see moderate voices and an inclusive cabinet as indicative of total oppression of BIPOC - then you've spent too long in the echo chamber of your own devising.
Could be that Biden and Harris have spottted that BIPOC aren't a homogenous group? That there might be a diversity of opinion here which pulls the conversation in different directions. Could it be they are attempting to return everyone to a centre ground position where moderation and solutions can be presented and discussed without sentences like 'The climate of active white terrorists'.
The other option is, of course, denouncing everyone that doesn't share your particular viewpoint of 'everything is white supremacist all the time' - as racism and oppression in action. The image you've selected for this article is so far removed from the reality of the Biden administration that you're starting to get into self-parody territory. If your view of the world isn't followed to the letter by every person regardless of skin colour, they're either race-traitors or they're oppressors.
Don't worry, I'll do it for you. Argumentative Penguin this comment is racist and you're clearly a white supremacist. Like Senator Tim Scott and Kamala Harris and slowly, inexorably, day by day every other person in the universe that isn't Ezinne Ukoha.
