Don’t worry here are some pretty solid sources from The CDC and various university and medical journals because, actually, I’m the one person here who has done my research
But I doubt you’ll read them! Because after that “genocide” comment it seems like you’re not just misinformed but worse - the type of person who would compare HUMAN GENOCIDE to the idea of tougher legislation on a breed of dog that kills living things more than any other domestic pet.
