Interestingly you’ve still not stated what your bosses issues was, other than your title where he has said you were racially insensitive.
Quite frankly are you sure you know ethnicity and heritage of everyone in your team? Are you going only by their skin tone? Do you know the ethnicity of their families. Their husbands their wives, maybe even their fostered or adopted children, their nieces and, nephews? Do you know where they grew up, where they went to school, who they lived with?
My friend is white, born and bred in London, she does not look racially ambiguous. Dark hair and pale skin. She has a Greek father and an Indian mother. Unless she told you you’d not know by looking at her . Another friend is also white, as are her parents, her sister married a black man, and her children, so my friends nephew and nieces are black. My daughters friend looks as British as they come. Her mother is Asian and her father is British, she spent many years living in poverty at a school where everyone’s second language was English, and she Excelled. One of the very very few.
Bottom line is whatever you said, your boss has said you were racially insensitive. And I can see where he is coming from. Every post is about you and your uniqueness. Whilst dismissing everyone else as Male, white and over thirty.
You seem to be making assumptions based on skin tone. Which is racially insensitive in the extreme, I refuse to believe you know the heritage and ethinicitt and wider family heritage of every single member of your team.
So I’d take a step back and stop focusing so much on you and your family circumstance and try to think of the other people in that room. Who they are, and don’t judge them by the colour of their skin, like you have done here, because unless you’ve met every one of them extended family your assumptions could be highly erroneous.
And as for your perception being unique. Every one of us has a unique perception. Due to our age, our heritage, where we grew up, our gender, even our class, our friends, our family.
You need to remember that when you look at a room full of people, you cannot judge them on the colour of their skin, and decide you alone are unique Because of it, then preach about victimisation, because when you do, you’re going to face situations like the one you’re know facing at work. A situation where you may rightly be guilty of racial insensitivity.
