It's not your life that might be on the line here, so how do you get off calling them "chickens?" In case you haven't noticed, tens of thousands of young and supposedly healthy people have been killed by this virus. There is absolutely no reason for people to expose themselves to any additional risk IF THEY DON'T WANT TO. There is no law that says these people MUST play the US Open because Black Panther (and others) will get upset if they don't.They are chickens, but it's not just Halep or Barty. Or Nadal. Dozens of them. Their teams are also chickens, it's not like they are very old.
"Slim" does NOT mean zero. Of course it's highly unlikely that any of the tennis players at that level will die from the virus, but Grigor Dimitrov has already made public just how bad he still feels, more than a month after he contracted Covid-19.The chances of athletes dying are slim. How to skip a Slam?
No, you don't. Calling someone a chicken is not a sign of respect in any language.But I also respect their decisions.
