Vegan answer to: 'If you love animals, then why do you eat their food?"

I posted this reply to a Facebook-poster with this claim.
I hear arguments like that all days, so I am not amused. Anyways, that argument is as illogical as all other arguments that try to justify the consumption of animal products.
If everyone ate a plant-based diet, the food would suffice for everyone, both human and nonhuman animals: http://www.drmcdougall.com/video/expert_testimonies_oppenlander.htm
A person eating animal products is in total consuming more plants, since he/she is eating animals that are eating plenty of plants (e.g. a cow eats more than 10 times more than a human). If animals do have a moral value, we are not morally justified to use them, including not to consume them.

Please consider this:
“The details of the charges claim that Vick sponsored illegal dog fighting, gambled on dog fights and permitted acts of cruelty against animals on his property. The talk shows have been filled with talking heads from the "humane community" condemning dog fighting and calling for Vick to be punished. Nike and Reebok have suspended products endorsed by Vick.

Please let me be very clear from the outset: I think that dog fighting is a terrible thing.

But I must say that the Vick case rather dramatically demonstrates what I call our "moral schizophrenia" about animals.

That is, if one thing is clear, it is that we do not think clearly about our moral obligations to animals.

In this country alone, we kill more than 10 billion land animals annually for food. The animals we eat suffer as much as the dogs that are used in dog fighting.

There is no "need" for us to eat meat, dairy or eggs. Indeed, these foods are increasingly linked to various human diseases and animal agriculture is an environmental disaster for the planet. We impose pain, suffering and death on these billions of sentient nonhumans because we enjoy eating their flesh and the products that we make from them.

There is something bizarre about condemning Michael Vick for using dogs in a hideous form of entertainment when 99 percent of us also use animals that are every bit as sentient as dogs in another hideous form of entertainment that is no more justifiable than fighting dogs: eating animals and animal products."
