Tragically, I don’t think she is the slightest bit unique in her being a bully. I have seen (thankfully, from afar) several women who have all the villainy of tyrannical men, some who even possess a shrill degree of cruelty that men tend to avoid.
Nicolae Ceausescu was the evil tyrant of Romania, but it was his wife Elena, whose savagery was so great that it may have been the final straw of his dictatorship. Her final act was both a brutal crackdown by the secret police, and instructions that they should burn the dead bodies of those they killed to prevent their identification by their families.
I would have to agree that women, given the opportunity, can be the more cruel and ruthless ones. Tyranny must be resisted, even if it is wearing high heels and lipstick.
