"Viciousness is driven by hate" -- and so it's clear you think Ann is "vicious," because of her joke.
I guess you've already surrendered to the left's definitions.
Sometimes Ann is fierce. Sometimes she is vicious. I like her when she's fierce; I don't like her when she's vicious.
Perhaps hatred is too strong a word to associate with viciousness, but I would posit that the line between fierceness and viciousness is crossed when a person makes an attack because attacking is fun, rather than because it was necessary to counter a threat.
