I admit I’m racist
I’m of the opinion that racism is a rather natural tendency of all of humanity. I group it under the umbrella of tribalism, thus relating to other groups that get stereotyped and/or pre-judged, like political affiliation, region (North/South, East/West Coast, etc), class, etc. I am not immune to such cognitive biases. I don’t think anyone is.
That’s not to say that I embrace it, but think it’s better to acknowledge a natural tendency so I’m more able to recognize it and reassess my initial perception. In other words, I’d rather consider myself a racist in hope of remedying that, rather than convince myself that I’m pure and unbiased (which is itself yet another bias).
