Taste Pleasure

What would be the best description for the fallacy that attempts to justify killing animals for the sake of taste pleasure?

All I'm ever able to muster up in response to this sort of reasoning is something along the lines of "Those two ideas just aren't in the same moral ballpark"

Is there such a thing as a not-in-the-same-moral-ballpark fallacy?!

Or perhaps the fallacy lies with me; I'm not sure.

Any help with this one would be great!
