Deny an accusation of calling for someone to be fired and point out your criticism of their tweet. Question the logic of the other person's response.
I never said Frei should be fired. I just said it was a dumb Tweet that didn't make any sense - about 30 minutes before you admitted it was a boneheaded Tweet. Not sure how that makes me PC and overly sensitive while you're the ever-so-rational voice of reason, but I'm sure you'll get around to explaining it at some point.
