Not people like you. People from different walks of life. Old people. Black people. Muslims. Fishmongers.”
Carry on, Britain
Lucy Chambers

I know this isn’t intended — but “Not people like you… Black people. Muslims.” comes across jarringly exclusionary! I’d guess (hope?!) some other people of colour would be reading this too, and this quote from your friend’s piece makes it sound like it’s written for white people to read and learn from, which I’m sure is the opposite of the intended advice on increasing diversity in your personal networks.
