That which does not affect you, you often do not see or understand
In other words, if you are White, 99% of the time Racism doesn’t affect you. Therefore, you may not see nor understand Racism when it happens.
If you are a Man, 99% of the time Sexism doesn’t affect you. Therefore, you may not grok Sexist behavior when it occurs nor will you always see Sexism when it is plain to others.
This goes for any -ist or -ism or -phobia you can think of. This goes for you, even if you’re a minority, when it concerns people who are not like you.
What does not affect you personally often will not impact on your consciousness unless you’ve trained yourself to see and understand.
Therefore, the next time you feel yourself declaring something “not racist” or “not sexist” or “not offensive”, think about whether you feel that way because you’re not the one on the receiving end of racist, sexist, or offensive behavior/words/actions/images.
