Weird but cool connection between fiction and reality

I was doing my book report for English, and I'm doing it on Harry Potter and the Deathly Hallows. I know a lot of people have read that book, and that it's a really big hit, but i don't know if anyone made this connection, or maybe I'm just crazy.
As i was remembering the part where Harry, Ron, and Hermione break into the Ministry after Voldemort has taken control of it, and seeing the statue of the witch and wizard sitting on chairs that are really made of humans (muggles), and it kind of dawned on me that Voldemort's whole philosophy of enslaving the muggles, and killing those who oppose, including half-bloods and mud-bloods, is almost exactly like a Hitler or Stalin philosophy. Probably not exactly, but it's really close.
I'm sure there are probably lots of other people that have figured this out, but i just thought it was kinda cool.
