Earthquake, I agree that calling it “Kung flu” can be considered demeaning.
But calling it by where it came from I don’t see it as racist at all.
And if some idiots attack Asian people because of it, it has nothing to do with the fact that where it came from as racist. These people had to be racists in the first place. Just like the racists that rioted and attacked and even killed innocent people during the recent riots.
Racists will look hard for reasons to make excuses for their racist behavior.
That’s how I see it, at least.
