The list of threats continues to grow...
I'll get corona... from a racist.
People have wondered recently what 'systemic racism' means, so I checked Wikipedia:
"Institutional racism (also known as systemic racism) is a form of racism that is embedded as normal practice within society or an organisation."
Does wearing a mask to slow the spread of COVID-19 have anything to do with the above definition? Not at first glance. But given how minorities are suffering disproportionately from this disease, I'll at least argue that refusing to make every reasonable personal sacrifice to slow the spread is racist.
And if the justification for doing otherwise invokes imitation - well, other people are walking around without masks, it's normal practice within society - then I refer you to the above definition.
