Absolutely, but I've made no appeal to nature. The only part which may be confused as an appeal to nature is when I said that this issue is unlike slavery in that meat has played a crucial role in forming us. This is not to say that the moral question should be avoided, only that it's complicated. Calling human desire for meat "a taste" is like calling our desire for art or stories "a taste". Neither meat nor art is crucial to our survival, but they are both an important part of what has made us human.
You could say that, unlike art, eating meat causes suffering, to which I'd answer that our existence causes suffering. The crux of my argument is this: no matter what we do, as long as we live on this planet we will be killing animals, lots of them, and in very cruel ways. We might do it directly or indirectly, but there is no way to avoid it. When we approach the moral question this is something we must bear in mind. We might decide that it's better to grow tomatoes and slowly starve animals to death rather than slaughter them. But we cannot avoid killing them.
If your goal is to minimize suffering, then I'd say we should go back to being hunters-gatherers. But we can't, because technological progress is also an integral part of who we are. So we choose progress and death to animals. Now the question remains whether within these confines we should minimize animal suffering caused directly by humans wearing blood-stained clothes. Maybe. As I've said in the beginning of my original comment, human values change.
