Rush was being absurd.
He said that since she was asking for enough money to pay for several protected sexual encounters a day that makes her a slut.
He said that since she was expecting the public to pay so she could have sex, that makes her a prostitute.
He could have just called her a LIAR and said that her bogus numbers were inflated.
But she’d still be a publicity whore.
You’re right. If nothing else, he should have waited til he could review what she said carefully.
