I'm definitely human = animal
and I've definitely had the odd medical condition = disease
I take it you're not much of a dog fan?
A quote which sums it up much more eloquently than I can:
"Once someone is dehumanised", we "deny them the consideration, compassion and empathy" that we would usually give other human beings, relaxing our "instinctive aversion" to "aggression and violence" towards our fellow humans.
