How the fuck do YOU do video conferences exactly?! Do you set your laptop up and then just face the other way with your back to the camera or something and NOT look at the onscreen people you're supposed to be talking to? Why would you assume that the guy is "doing something wrong" when there is absolutely no indication of this? You're going through mental gymnastics and trying your hardest to dream up a scenario where the Asian person is at fault just to excuse racist comments and it's disgusting.

Like when the two black guys at Starbucks got the cops called on them for "being suspicious", you'd be the person going "I bet they were acting all aggressive and intimidating to the barista and deserved it" when it has absolutely no basis for that assumption other than your inability to stomach the truth.
