When he's laying down the law to the winter court:
My voice echoed throughout the whole chamber as clearly as if I’d been using a PA system. “All right, you primitive screwheads. Listen up. I’m Harry Dresden. I’m the new Winter Knight. I’m instituting a rule: When you’re within sight of me, mortals are off-limits.” I paused for a moment to let that sink in. Then I continued. “I can’t give you orders. I can’t control what you do in your own domains. I’m not going to be able to change you. I’m not even going to try. But if I see you abusing a mortal, you’ll join Chunky here. Zero warnings. Zero excuses. Subzero tolerance.”
I paused again and then asked, “Any questions?” One of the Sidhe smirked and stepped forward, his leather pants creaking. He opened his mouth, his expression condescending. “Mortal, do you actually think that you can—” “Infriga!” I snarled, unleashing Winter again, and without waiting for the cloud to clear, hurled the second strike, shouting, “Forzare!” This time I aimed much of the force up. Grisly bits of frozen Sidhe noble came pattering and clattering down to the ice of the dance floor.
When I first read this I did a mental double-take. Harry committed murder there. Seriously, he straight up murdered a sapient being for the crime of disagreeing with him, and somehow it's okay because it was a Sidhe, not a human. And nobody calls him out on it. There have been other instances of speciesism in the series, but this takes the cake.
A) It wasn't that the sidhe was disagreeing with Harry, it was
what he was disagreeing with. Harry told them that they cannot kill or torture mortals -- who are
also sentient beings -- while in his presence. The sidhe in question piped up with the equivalent of "you can't tell us what to do!" It wasn't that he wasn't human, it was the fact that he seemed to be active condoning the kidnapping/murder/torture/rape of innocents. Harry would've reacted similarly to mortals who did the same. It
would be speciesism if Harry treated the sidhe differently because "ah, he's a faery, that's who they are."
B) The winter sidhe don't seem to respect much aside from violence and power. Harry knew that there was no other way of enforcing his rules in about the two seconds that he had to make a decision.
C) Harry's
never claimed to be completely morally correct guy, or a non-hypocrite.
