my kids' elementary school, so got to know the (terrifying) principal of the school and her tactics pretty well. I'd described them to my husband, and when he finally met her he was even more appalled than I. Because of her height, attire (forties' style straight suits), physique, and hairstyle (I kid you not: two dark braids coiled from both sides onto the top of her head), he dubbed her "Helga, She-Wolf of the SS." That moniker stuck for a number of years, until the kids graduated and she left, to everyone's relief.

She was not, to my knowledge, a Holocaust denier of any sort, but she was a dictator and cold-hearted. (We parents had organized a series of evening sessions to meet with the many Hmong parents of the kids in our school, to help them negotiate the cultural and educational waters and to listen to their concerns, in order to develop and implement policies that could address their needs. We had even arranged for translators. She vehemently forbade this, but we won out in the end.)

At any rate, your OP may be a little over the top, but I had to laugh at the remembrance of "Helga, She-Wolf of the SS."
