We all have attitudes and judgments that we hold against people or groups, and we can only begin to let go of those prejudices if we admit that. When I was in university, one of my professors had a profound impact on me when she said to us, "Don't ask yourself if you are racist; ask yourself how you are racist." We all have strong inclinations to answer no when asked if we are racist, but when we ask ourselves how instead, that can be an invitation for self-reflection.
I find that the best starting point for me is to examine my privilege as a white, middle-class, educated professional woman. From within this sphere of privilege, I know that I make assumptions about other individuals or groups of people regardless of their race, ethnicity, political affiliation, and so on.
Unconsciously or not, I am sure I bring those judgments out into the world. I can do better when I know better.
Do you ask yourself the hard "how" questions, or do you take the easy "if" way out? None of us are without prejudices; we need to admit that to change and grow.
It's one of the ways we can keep our side of the street clean in recovery.
