No, I would like to reduce suffering and make slaughterhouses and factory farms safer and healthier places to be. I have compassion for animals. I grant that they feel pain and pleasure - ie sentinece. I'd rather they feel more of the latter and less of the former.
I grant them moral consideration. It is immoral to abuse an animal, to cause it pain for fun or due to carelessness.
But animals are not sapient. Animals are not people. And equating the suffering of an animal, however bad it may be, with the suffering of people who were mentally and physically enslaved, or to the Holocaust as PETA has done is ignorant in the extreme. We're particular about our domesticated animals. We've bred some to eat, some for companionship and some basically adopted us as convenient food sources (cats I'm looking at you) but we they are still animals.
I love my cat, and i have a responsibility to her to care for her, but I would save a human before saving her. She's bonded to me on her part as best as she can be, as a mother or littermate. But she can't love me and she isn't even aware that she can't. If you find humans and animals completely equal in value, then at least you can argue consistency, I suppose. But that's a rather weak argument overall.
I largely agree with you, and I do not think that myself of Sum of Awe or most people who rally for animal rights actually think that animals experience life exactly as humans do. In fact, I think every animal species will have some different experience of life and sensation and emotion etc.
Generally bringing up slavery, as I have already mentioned, is not about arguing that all animals are exactly the same as humans. But I do still consider it slavery and abuse, the way animals are generally treated by human beings.
I apologise for my misunderstanding of your view. I think we agree mostly.
