While I agree that the holocaust was done for different reasons, the holocaust was done for fear, hatred and power, and this is done for power, ignorance and greed, I do think they are just as bad.
If anything what we do to animals is worse. In the holocaust there were millions of individuals killed, but in this there are billions, every year.
I am not sepciesist, and if a non-human animal can suffer the same as a human, then I see no reason to treat the nonhumans suffering as less important than the humans suffering.
I also see not reason that just because they're done for different reaons, the one should be taken less seriously than the other. It doesn't really make much difference to the victims WHY they're being tortured and killed.
(that's all IMHO of course).
