As much as I like the cons of the article:
I find the “pros” partly a bit superficially treated.
Point 1. homocentrists and speciesist don’t care really wheather it’s “unnecessary” today to eat flesh. It’s about sacrificing life. Like “my human life is worth more than … “.
Point 2. Again, underlying mechanisms in society are overlooked when we hold back in as much that veganism (or rather not wanting to take part in animal murder in any form) is solely a choice of personal decision. The part of neseccisty on the side of “what human rights lose in a speciesist society” would need to be addressed for instance.
Point 3. It needs to be explained why a nonhuman animal victim isn’t even considered a victim by a speciesist or homocentrist respectively. “No being who prides himself on rationality can continue to support such behaviour.” Exactly that is the problem, they say that just because they are “rational” they are allowed to kill for their taste buds, etc.
Point 4. The destructivity of meat eating has the speciality that it does not care that it destroys the earth AND other humans (partly direclty) too … . To believe in the false cloak of a “humanity” that bases itself on speciesism and homocentrism, means to fall for a dangerous contractualism:
I don’t buy that people really in a basic sense accept even other humans rights. They don’t even accept my human right for example that I consider nonhuman animals to be rights holders as personalities too. So to believe that a person basically has a sense for “rights” but only applies it to her or his group seems wrong to me, BECAUSE this would be ONLY a contractualism, but with the claim for animal rights we are looking for the basic, fundamental rights to life, and earth-/ independent environmental rights, etc.
Point 5. here again it should be highlighted more or at all how animal rights and humans rights are intertwined – in a positive sense.
Otherwise I find it good and always highly due to discuss the issue of rights, in particular and foremostly animals rights and human “personal” choices!
