Some things about it here: I don't see how not wanting to respect a cockroach makes me a xenophobe. Really, that line of thinking made no sense whatsoever. Like I said, I don't treat anther species like mine (actually, nobody does), also, I won't treat my own species like another. The primary failure with this argument is that it assumes something wrong about me, and one that doesn't even makes sense!
OK, who made us "stewards of this planet"? God? I don't believe in gods, you'll have to do better. And then again, you assume something I never said I did: That I don't treat other animals as sensitive, conscious creatures who can feel things. Please, go to parent; I never said that. I said I don't treat them like humans. Because they are not. We won't understand some animals' concepts (because first and foremost we lack some ways to sense the environment that they have, and they lack senses that we have) and they won't understand most of our ways an values.
About ans and taxes, I meant it literally. If you treat animals like humans, they should have the same rights and be subject of the same laws as us. Or you think they only should have the rights and their responsibilities should be transferred to their.... well, in this possibility it's not possible to use "owner", so let's say "partner"? Because that's not equal treatment; animals would be superior to us.
And for last, if a "superior" (I don't know what consists of "superior" here, really) species used us for food, I'm pretty sure that what I feel about it wouldn't have the least importance. I'd be foodstuff. If I knew I would be killed for food, I would probably hope for a long life and a quick death.
