Well yes you do. Steven Wise has no affiliation with HSUS or Peta for that matter. He is his own man, The Nonhuman Rights Project to be precise.
The ultimate dream for animal rights advocates would be something like the application of the 14th Amendment's equal protection to animals as well as humans. Such a ruling might ban the rearing of domesticated animals for meat altogether. And some major thinkers in the field -- most famously Steve Wise of the Nonhuman Rights Project -- are actively pursuing it.
"Right now, it's really easy to determine who has the capacity to have a right," he explained. "You look at the species. If you're human, you have rights. If you're not, you don't. What we're arguing is that species is completely arbitrary. There are many nonhuman animals that have really serious cognitive complexity. And we think that cognitive complexity alone is a sufficient condition to make some animals legal persons."
