Veganism?

[RW_9]

So am I. We do not have enough knowledge about a creature's consciousness yet to determine what role would it play in its personhood. But that shouldn't stop us from coming up with standards that would be applied once the knowledge does come into picture.

There have been standards applied to our current knowledge. If you disagree with the current standards in society (whichever you happen to be in), feel free to make an argument against them. At present time, the broad standard is that of the human species. If you are a proponent of calling that specieism and wish to include the rights of personhood to other species, feel free to make an argument for it. Virtually nobody will listen, but that's because Singer already came up with arguments for it and society dismissed him.
