Hey ... I'm a big brown long haired red skinned Indigenous person ... you can see me coming from a mile away.
I've had people scream, yell, say, suggest, comment, off the cuff, passive-aggressively, overtly, covertly, obviously, secretly and blatantly be racist to me behind my back and to my face many many times ... more often passively but a few times openly and blatantly. I've had some pretty ugly things said to me either directly or indirectly because of the colour of my skin and what I look like.
I think some old white guy with a good station in life can handle being called a 'boomer' online.
